Question 1.
Elsa is knitting a blanket. She used 4\(\frac{3}{8}\) meters of red yarn and 2\(\frac{4}{8}\) meters of gold yarn. How many meters of yarn did she use altogether?
Answer:
6\(\frac{7}{8}\) meters

Explanation:
Elsa is knitting a blanket
She used 4\(\frac{3}{8}\) meters of red yarn and
2\(\frac{4}{8}\) meters of gold yarn
Add to find the total number of meters of yarn
4\(\frac{3}{8}\) + 2\(\frac{4}{8}\) = 6\(\frac{7}{8}\) meters
So, Elsa used 6\(\frac{7}{8}\) meters of yarn altogether.

McGraw Hill Math Grade 4 Chapter 10 Lesson 7 Answer Key img 1

Explanation:
Ms. Morton has 167\(\frac{3}{5}\) cm of string
She cuts the string into two pieces
One piece is 72\(\frac{1}{5}\) cm long
Subtract to find the length of the other piece
167\(\frac{3}{5}\) – 72\(\frac{1}{5}\) = 95\(\frac{2}{5}\)
So, the other piece is 95\(\frac{2}{5}\).
