Question

7. Joni has 4 yards of ribbon. How many centimeters is that? 1 inch ~ 2.54 centimeters, 1 yard = 3 feet, 1 foot = 12 inches *

Answer 1

365.76 cm

Explanation:

Let's go down units one by one

1 yard = 3 feet

1 yard / 3 feet = 1

3 feet / 1 yard = 1

multiply 4 yards by 1 to ensure equality, but put the yard unit at the bottom so the yards cancel out

4 yards * 1 = 4 yards * 3 feet / 1 yard = 12 feet

1 foot = 12 inches

12 inches / 1 foot = 1

12 feet * 12 inches / 1 foot = 144 inches

1 inch = 2.54 cm

2.54 cm / 1 inch = 1

144 inches * 2.54 cm / 1 inch = 365.76 cm
