Question

10. Maddie has 28.14 ounces of yarn. Each scarf requires 5.25 ounces of yarn. How many scarves can she make and still have at least 3.5 ounces left over to make two pairs of mittens? Show your work.​

Answer 1

To determine how many scarves Maddie can make and still have at least 3.5 ounces of yarn left over, we can use division and subtraction.

First, we need to figure out how much yarn Maddie will use to make two pairs of mittens:

2 pairs of mittens x 2 mittens per pair x 2.25 ounces of yarn per mitten = 9 ounces of yarn

Next, we can subtract the amount of yarn needed for the mittens from the total amount of yarn Maddie has:

28.14 ounces of yarn - 9 ounces of yarn = 19.14 ounces of yarn remaining

Now, we can divide the remaining amount of yarn by the amount needed for each scarf to find out how many scarves Maddie can make:

19.14 ounces of yarn ÷ 5.25 ounces of yarn per scarf ≈ 3.64 scarves

Since Maddie can't make a fraction of a scarf, we need to round down to the nearest whole number. Therefore, Maddie can make 3 scarves and still have at least 3.5 ounces left over to make two pairs of mittens.
