Pima Medical Institute Wonderlic Practice Test – Prep, Study Guide & Practice Exam

To determine the number of skeins of yarn needed, we first need to convert all measurements to the same unit. The problem states that 36 yards of yarn are required, and each skein contains 6 feet of yarn.

First, convert yards to feet. Since there are 3 feet in a yard, we multiply the number of yards by 3:

36 yards × 3 feet/yard = 108 feet.

Now we know that we need a total of 108 feet of yarn. Next, we'll find out how many skeins are necessary by dividing the total feet needed by the number of feet per skein:

108 feet ÷ 6 feet/skein = 18 skeins.

This calculation shows that for 108 feet of yarn, 18 skeins are required. Therefore, the correct answer is 18 skeins.
