Question

Kelli wants to sew trim around the sleeves and hem of a dance costume. She needs a piece of trim that is 8 1/8 inches long for the sleeves and a piece that is 40 5/8 inches long for the hem. If the package contains 5 feet of trim, how much trim will she have left after making the costume.

Answer 1

0.9375 feet of trim

Explanation:

Step 1

We find the total number of inches used

We are told : She needs a piece of trim that is 8 1/8 inches long for the sleeves and a piece that is 40 5/8 inches long for the hem.

Hence, the total = (8 1/8 + 40 5/8)inches = 48 3/4

= 48.75 inches

Step 2

We convert to feet

1 inch = 0.0833333 feet

48.75 inches = x

Cross Multiply = 48.75 × 0.00833333 feet

= 4.0625 feet

Hence, she would use 4.0625 feet of ribbon

If the package contains 5 feet of trim, how much trim will she have left after making the costume.

This is calculated as:

5 feet - 4.0625 feet

= 0.9375 feet of trim
