Question

Christopher Christopher just found beautiful yarn for 20% off at his favorite yarn store. He can make one scarf from 2/3 of a ball of yarn. If Christopher buys 12 balls of yarn, how many scarves can he make

Answer 1

2/3=.6 repeating
12/.6 repeating = 18
13 balls of yarn would be used to make 18 scarves.

Answer 2

Hello!

Let's convert 2/3 to a decimal and then divide 12 balls of yarn by that.

To convert a fraction to a decimal, we must divide its numerator by its denominator.

2 ÷ 3 = 0.67 (6 Repeating)

Now, divide 12 yarn balls by this:

12 ÷ 0.67 (Repeating) = 17.91 (Repeating decimal)

A N S W E R:

Christopher can make 18 scarves with 12 balls of yarn.
