Question

As the weather got colder, Rob knitted blankets for his friends: Dale, Mandy, Hanson, and Tina. He used 21 balls of yarn that he divided up evenly to make the blankets. How many balls of yarn did Rob use for each blanket?

Answer 1

Rob used 5 balls of yarn for each blanket when he divided 21 balls of yarn evenly among four blankets, with one ball of yarn left over.

Step-by-step explanation:

The question involves a basic division problem where Rob divided 21 balls of yarn evenly to make blankets for his four friends: Dale, Mandy, Hanson, and Tina. To find out how many balls of yarn Rob used for each blanket, we need to divide the total number of balls of yarn, 21, by the number of blankets he made, which is 4.

21 divided by 4 equals 5 with a remainder of 1. This means that Rob used 5 balls of yarn for each blanket, and there was one ball of yarn left over. In practical terms, he may have used the extra yarn to add details or simply kept it aside.
