💼 Career

Understanding number types helps you write correct calculations and avoid errors in software development.

1

Create integer variables

Create two integer variables called apples and oranges with values 10 and 5 respectively.

Ruby

# Create integer variables apples and oranges
# Your code here

Need a hint?

Use simple assignment like variable = value to create variables.

2

Create a float variable

Create a float variable called price_per_apple and set it to 0.75.

Ruby

apples = 10
oranges = 5
# Create a float variable price_per_apple
# Your code here

Need a hint?

Use a decimal number to create a float variable.

3

Calculate total cost

Create a variable called total_cost that multiplies apples by price_per_apple.

Ruby

apples = 10
oranges = 5
price_per_apple = 0.75
# Calculate total_cost by multiplying apples and price_per_apple
# Your code here

Need a hint?

Use the * operator to multiply numbers.

4

Print the total cost

Print the value of total_cost using puts.

Ruby

apples = 10
oranges = 5
price_per_apple = 0.75
total_cost = apples * price_per_apple
# Print total_cost
# Your code here

Need a hint?

Use puts total_cost to display the result.
