Chester needs 2 feet of ribbon for an art project, but his ruler only measures in centimeters. There are 12 inches in 1 foot and 2.54 centimeters in 1 inch. Chester multiplied 12 by 2 and then divided the product by 2.54 to find that he needs about 9.4 centimeters of ribbon. This length is much shorter than 2 feet, so he knows he is incorrect. Which of these would give Chester the correct number of centimeters of ribbon he needs?

Answer:

see the explanation

Step-by-step explanation:

step 1

Convert feet to inches

we know that

[tex]1\ ft=12\ in[/tex]

To convert feet to inches, multiply by 12

so

[tex]2\ ft=2(12)=24\ in[/tex]

step 2

Convert inches to centimeters

we know that

[tex]1\ in=2.54\ cm[/tex]

To convert inches to centimeters multiply by 2.54

so

[tex]24\ in=24(2.54)=60.96\ cm[/tex]

therefore

Chester should have multiplied the measurement in inches by 2.54 instead of dividing by 2.54
