Question

Each pants leg has an opening with a circumference of 8.5 inches. It took 15 stitches to make 3 inches in width. How many stitches make up the circumference, rounded to the nearest stitch?

Answer 1

No. of stitches = 43

Explanation:

Given:

15 stitches required to make 3 inches in width.

To find:

No of stitches to cover 8.5 inches circumference.

Assuming that the stitch length remains constant.

We know that no.of stitches is directly proportional to covered inches. This is problem of direct variation,

Inches Stitches

3 15

8.5 x

Here x is given by,

x = (8.5/3)*15

= 42.5

≅ 43 (rounding to the nearest)

Hence, No. of stitches that make up the circumference is 43
