💡 Hint

Common Mistakes

Using relative reference like A1 which changes when copied.

Fixing only row or column but not both.

Using $A$1 locks both the column and row, making the reference absolute.

2fill in blank

Complete the formula to fix only the column A when copying across columns.

Google Sheets

=B1*[1]

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

💡 Hint

Common Mistakes

Fixing both column and row which is too strict.

Not fixing the column, so it changes when copied.

$A2 fixes the column A but allows the row to change when copied down.

3fill in blank

hard

Fix the error in the formula to correctly lock the row 5 when copying down.

Google Sheets

=SUM(B[1]:D5)

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

C$5$

D5$

💡 Hint

Common Mistakes

Placing $ after the number which is invalid.

Not using $ so the row changes when copied.

$5 locks the row 5 while allowing the column to change.

4fill in blank

hard

Fill both blanks to create a formula that multiplies the fixed cell B1 by cells in column C.

Google Sheets

=C[1]*[2]

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

CB1

D$C$1

💡 Hint

Common Mistakes

Using relative reference for B1 which changes when copied.

Fixing the wrong cell or row.

The row 2 is relative to multiply with C2, and $B$1 fixes the cell B1.

5fill in blank

hard

Fill all three blanks to create a formula that sums a fixed range from A1 to C1 and multiplies by the value in D2.

Google Sheets

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

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

💡 Hint

Common Mistakes

Not fixing the sum range cells, so the range changes when copied.

Using wrong multiplier cell.

$A$1 and $C$1 fix the sum range, and D2 is the multiplier.

Practice

1. What does an absolute reference like $A$1 do in Google Sheets?

easy

A. It locks only the row but allows the column to change when copied.

B. It locks only the column but allows the row to change when copied.

C. It locks both the column and row so the reference doesn't change when copied.

D. It allows both the column and row to change when copied.

Solution

1. Step 1: Understand absolute references

   An absolute reference uses $ before the column letter and row number to fix both.

2. Step 2: Effect when copying formulas

   When copied, the reference $A$1 stays exactly the same, not changing column or row.

3. Final Answer:

   It locks both the column and row so the reference doesn't change when copied. -> Option C

4. Quick Check:

   Absolute reference = fixed column and row [OK]

Hint: Look for $ before both column and row to lock both [OK]

Common Mistakes:

• Thinking $ locks only one part without checking both
• Confusing relative and absolute references
• Assuming $ allows changes when copying

2. Which of the following is the correct syntax for an absolute reference to cell B3 in Google Sheets?

easy

A. $B$3

B. B$3$

C. $3$B

D. 3$B$

Solution

1. Step 1: Recall absolute reference format

   Absolute references use $ before the column letter and row number, like $B$3.

2. Step 2: Check each option

   Only $B$3 correctly places $ before column B and row 3.

3. Final Answer:

   $B$3 -> Option A

4. Quick Check:

   Correct absolute reference syntax = $Column$Row [OK]

Hint: Always put $ before column letter and row number in order [OK]

Common Mistakes:

• Placing $ after row or column
• Swapping column letter and row number
• Using numbers before letters

3. If cells A1 and A2 contain 10, cell B1 contains the formula =A1*$C$1, and C1 contains 5, what will be the value in B2 after copying the formula from B1 to B2?

medium

A. 5

B. 10

C. Error

D. 50

Solution

1. Step 1: Understand formula in B1

   The formula multiplies A1 (10) by $C$1 (5). $C$1 is absolute, so it stays fixed.

2. Step 2: Copy formula to B2

   When copied to B2, A1 becomes A2 (10), but $C$1 stays fixed at 5. Result is 10*5=50.

3. Step 3: Assume A2 same as A1 (10)

   Value in B2 = 10 * 5 = 50.

4. Final Answer:

   50 -> Option D

5. Quick Check:

   Absolute reference keeps C1 fixed, so 10*5=50 [OK]

Hint: Absolute $C$1 stays fixed; relative A1 changes to A2 [OK]

Common Mistakes:

• Assuming $C$1 changes when copied
• Ignoring relative reference change from A1 to A2
• Confusing values in cells

4. You have the formula =SUM(A1:A5)*$B$1 in cell C1. When you copy it to cell C2, the formula changes to =SUM(A2:A6)*$B$1. But you want the range to stay A1:A5. How do you fix the formula?

medium

A. =SUM(A$1:A$5)*$B$1

B. =SUM($A$1:$A$5)*$B$1

C. =SUM($A1:$A5)*$B$1

D. =SUM(A1:A5)*B1

Solution

1. Step 1: Identify why range changes

   Range A1:A5 is relative, so when copied down, it shifts to A2:A6.

2. Step 2: Use absolute references for range

   To keep range fixed, add $ before column and row: $A$1:$A$5.

3. Step 3: Check options

   Only =SUM($A$1:$A$5)*$B$1 uses full absolute references for the range and keeps $B$1 fixed.

4. Final Answer:

   =SUM($A$1:$A$5)*$B$1 -> Option B

5. Quick Check:

   Absolute range locks cells, so range stays same when copied [OK]

Hint: Add $ before both column and row in range to fix it [OK]

Common Mistakes:

• Using partial $ causing only column or row to fix
• Not fixing the range at all
• Removing $ from $B$1 accidentally

5. You want to create a formula in cell D2 that multiplies the value in column B of the same row by the fixed tax rate in cell $F$1. You plan to copy this formula down the column. Which formula should you use in D2?

hard

A. =B2*$F$1

B. =$B$2*F1

C. =B$2*$F1

D. =$B2*$F1

Solution

1. Step 1: Identify relative and absolute parts

   The value in column B changes by row, so B2 should be relative (no $). The tax rate in F1 is fixed, so $F$1 is absolute.

2. Step 2: Check formula options

   =B2*$F$1 uses B2 (relative) and $F$1 (absolute), perfect for copying down.

3. Step 3: Verify copying behavior

   When copied down, B2 becomes B3, B4, etc., but $F$1 stays fixed, applying the same tax rate.

4. Final Answer:

   =B2*$F$1 -> Option A

5. Quick Check:

   Relative row for B, absolute for tax rate cell [OK]

Hint: Use relative for row-changing cells, absolute for fixed constants [OK]

Common Mistakes:

• Fixing B2 with $ causing no row change
• Not fixing tax rate cell causing errors
• Mixing $ placement incorrectly
