Practice - 5 Tasks

1fill in blank

easy

Complete the formula to always refer to cell A1, even when copied.

Excel

=SUM([1])

Drag options to blanks, or click blank then click option'

A$A$1

BA$1

C$A1

DA1

💡 Hint

Common Mistakes

Using relative reference like A1 causes the cell to shift when copied.

Using only one $ locks either row or column, not both.

Using $A$1 locks both the column and row, so the reference does not change when copied.

2fill in blank

medium

Complete the formula to multiply the value in B2 by the fixed value in C1.

Excel

=B2*[1]

Drag options to blanks, or click blank then click option'

A$C$1

BC1

CC$1

D$C1

💡 Hint

Common Mistakes

Using relative reference C1 causes the reference to shift.

Using partial absolute references locks only row or column.

Using $C$1 keeps the reference fixed to cell C1 when copying the formula.

3fill in blank

hard

Fix the error in the formula to always sum the range A1:A5 when copied.

Excel

=SUM([1])

Drag options to blanks, or click blank then click option'

AA1:A5

B$A1:$A5

CA$1:A$5

D$A$1:$A$5

Attempts:

3 left

💡 Hint

Common Mistakes

Using relative range A1:A5 shifts the range when copied.

Partial absolute references lock only part of the range.

Using $A$1:$A$5 locks the entire range so it does not change when copied.

4fill in blank

hard

Fill both blanks to create a formula that multiplies the value in D3 by the fixed value in E2.

Excel

=D3*[1]+[2]

Drag options to blanks, or click blank then click option'

A$E$2

BE2

C$E2

DE$2

Attempts:

💡 Hint

Common Mistakes

Using relative references for both blanks causes errors when copying.

Using absolute references for both blanks may not be intended.

The first blank uses $E$2 to keep the reference fixed. The second blank uses E2 as a relative reference.

5fill in blank

hard

Fill all three blanks to create a formula that sums a fixed range and multiplies by a fixed cell.

Excel

=SUM([1])*[2]+[3]

Drag options to blanks, or click blank then click option'

A$A$1:$A$10

B$B$1

C$C$1

DA1:A10

Attempts:

💡 Hint

Common Mistakes

Using relative references causes the formula to change unexpectedly when copied.

Mixing relative and absolute references incorrectly.

The range $A$1:$A$10 is fixed for summing. The cells $B$1 and $C$1 are fixed for multiplication and addition.

Practice

1. What happens to a relative cell reference like A1 when you copy a formula from one cell to another?

easy

A. It changes based on the new cell's position

B. It stays exactly the same

C. It causes an error

D. It becomes an absolute reference automatically

Solution

1. Step 1: Understand relative references

   Relative references adjust when copied to reflect the new position relative to the original cell.

2. Step 2: Apply to copying formula

   Copying a formula with A1 from one cell to another changes the reference to match the new location.

3. Final Answer:

   It changes based on the new cell's position -> Option A

4. Quick Check:

   Relative reference = changes when copied [OK]

Hint: Relative references shift when copied; absolute do not [OK]

Common Mistakes:

• Thinking relative references stay fixed
• Confusing relative with absolute references
• Assuming copying causes errors

2. Which of the following is the correct way to write an absolute reference to cell B2 in Excel?

easy

A. B$2

B. $B2$

C. B2$

D. $B$2

Solution

1. Step 1: Recall absolute reference syntax

   Absolute references use dollar signs before both column letter and row number, like $B$2.

2. Step 2: Check options

   Only $B$2 correctly locks both column and row.

3. Final Answer:

   $B$2 -> Option D

4. Quick Check:

   Absolute reference = $ before column and row [OK]

Hint: Use $ before column and row for absolute reference [OK]

Common Mistakes:

• Placing $ after row or column
• Using only one $ for absolute reference
• Confusing mixed and absolute references

3. If cell C1 contains the formula =A1+B1 and you copy it to cell C2, what will the formula in C2 be?

medium

A. =A1+B1

B. =A2+B2

C. =$A$1+$B$1

D. =C1+D1

Solution

1. Step 1: Understand relative references in formula

   The formula =A1+B1 uses relative references, so both A1 and B1 will shift down by one row when copied to C2.

2. Step 2: Apply copying to C2

   Copying down one row changes references to A2 and B2.

3. Final Answer:

   =A2+B2 -> Option B

4. Quick Check:

   Relative references shift with copy [OK]

Hint: Relative references adjust row and column when copied [OK]

Common Mistakes:

• Assuming references stay the same
• Confusing absolute and relative references
• Using wrong cell references after copy

4. You have the formula =SUM($A1:B$2) in cell C3. When copied to cell D4, what is the corrected formula to keep the intended reference range?

medium

A. =SUM($A2:C$2)

B. =SUM($A1:C$2)

C. =SUM($A1:B$2)

D. =SUM(A1:B2)

Solution

1. Step 1: Analyze mixed references in original formula

   $A1 locks column A but row changes; B$2 locks row 2 but column changes.

2. Step 2: Calculate new references after copying from C3 to D4

   Moving one column right and one row down changes $A1 to $A2 and B$2 to C$2.

3. Final Answer:

   =SUM($A2:C$2) -> Option A

4. Quick Check:

   Mixed references adjust unlocked parts when copied [OK]

Hint: Mixed references lock only column or row, adjust the other [OK]

Common Mistakes:

• Not adjusting unlocked row or column
• Assuming absolute references change
• Copying formula without updating references

5. You want to create a formula in cell D5 that multiplies the value in cell B2 by a fixed tax rate in cell $A$1, then copy this formula down column D. Which formula correctly uses reference types to keep the tax rate fixed?

hard

A. =B$2*$A1

B. =$B$2*A1

C. =B2*$A$1

D. =$B2*A$1

Solution

1. Step 1: Identify fixed and relative references needed

   The tax rate in $A$1 must stay fixed when copying, so it needs absolute reference. The value in B2 should change row when copied down, so it stays relative.

2. Step 2: Check formula correctness

   =B2*$A$1 keeps tax rate fixed and adjusts B2 row as copied down.

3. Final Answer:

   =B2*$A$1 -> Option C

4. Quick Check:

   Absolute reference locks tax rate; relative adjusts data cell [OK]

Hint: Use $ to lock tax rate cell; leave data cell relative [OK]

Common Mistakes:

• Locking data cell instead of tax rate
• Not locking tax rate cell causing errors
• Using mixed references incorrectly
