McGraw-Hill Math Grade 4 Answer Key Chapter 8 Lesson 8 Problem Solving: Draw a Picture and Write an Equation
Solve
Question 1.
Ms. Robinson and her son hiked three trails with the following lengths: 5\(\frac{2}{9}\) mile; 1\(\frac{1}{9}\) mile; and 1\(\frac{4}{9}\) mile. How far did they walk in all?
Answer:
7\(\frac{7}{9}\) miles
Explanation:
5\(\frac{2}{9}\) mile; 1\(\frac{1}{9}\) mile; and 1\(\frac{4}{9}\) mile.
The Denominators of the given fractions are same so add the numerators.
5\(\frac{2}{9}\) + 1\(\frac{1}{9}\) + 1\(\frac{4}{9}\)
\(\frac{2}{9}\) + \(\frac{1}{9}\) + \(\frac{4}{9}\) = \(\frac{7}{9}\)
5 + 1 + 1 + \(\frac{7}{9}\) = 7\(\frac{7}{9}\) miles
Question 2.
Ms. Tanaka is making a fruit salad for a party. She uses 6\(\frac{6}{8}\) cups of grapes, 3\(\frac{1}{8}\) cups of melon cubes, and 4\(\frac{4}{8}\) cups of orange slices. How many more cups of grapes does she use than orange slices?
Answer:
Given,
Ms. Tanaka is making a fruit salad for a party. She uses 6\(\frac{6}{8}\) cups of grapes, 3\(\frac{1}{8}\) cups of melon cubes, and 4\(\frac{4}{8}\) cups of orange slices.
6\(\frac{6}{8}\) – 4\(\frac{4}{8}\)
\(\frac{6}{8}\) – \(\frac{4}{8}\) = \(\frac{2}{8}\) = \(\frac{1}{4}\)
6 – 4 = 2
2 + \(\frac{1}{4}\) = 2\(\frac{1}{4}\)
Thus she use 2\(\frac{1}{4}\) cups of grapes than orange slices
Question 3.
A fabric store sold 8\(\frac{5}{9}\) yards of black felt and 4\(\frac{4}{9}\) yards of red felt on Tuesday. How many more yards of black felt than red felt were sold?
Answer:
Given,
A fabric store sold 8\(\frac{5}{9}\) yards of black felt and 4\(\frac{4}{9}\) yards of red felt on Tuesday.
8\(\frac{5}{9}\) – 4\(\frac{4}{9}\)
\(\frac{5}{9}\) – \(\frac{4}{9}\) = \(\frac{1}{9}\)
8 – 4 = 4
= 4\(\frac{1}{9}\) yards
Thus black felt sold 4\(\frac{1}{9}\) yards than red felt.
