Unit 3 Lesson 8 Solve Real World Problems Math Expressions Question 1.
Answer:
0.875 + 0.75 = 1.625.
0.875 . 0.75 = 0.656.
0.875 – 0.75 = 0.125.
Explanation:
In the above-given question,
given that,
the fractions are 7/8 and 3/4.
add, multiply, subtract the fractions.
7/8 + 3/4.
7/8 = 0.875.
3/4 = 0.75.
0.875 + 0.75 = 1.625.
0.875 . 0.75 = 0.656.
0.875 – 0.75 = 0.125.

Unit 3 Lesson 8 Math Expressions Solve Real-World Problems Question 3.
The Eagle Trucking Company must deliver \(\frac{7}{8}\) ton of cement blocks and \(\frac{5}{8}\) ton of bricks to one place. How much will this load weigh?
Answer:
The weight of the load = 1.5 tons.
Explanation:
In the above-given question,
given that,
The Eagle Trucking Company must deliver \(\frac{7}{8}\) ton of cement blocks and \(\frac{5}{8}\) ton of bricks to one place.
7/8 + 5/8.
7/8 = 0.875.
5/8 = 0.625.
0.875 + 0.625 = 1.5.
so the weight of the load = 1.5 ton.
Lesson 8 Answer Key Math Expressions Solve Real-World Problems Question 4.
A truck carried 3\(\frac{1}{3}\) tons of sand, but lost \(\frac{1}{4}\) ton along the way. How many tons of sand were delivered?
Answer:
The number of tons of sand that were delivered = 3.05.
Explanation:
In the above-given question,
given that,
A truck carried 3\(\frac{1}{3}\) tons of sand, but lost \(\frac{1}{4}\) ton along the way.
3(1/3) – 1/4.
10/3 – 1/4.
3.3 – 0.25.
3.05.
so the number of tons of sand was delivered = 3.05.
Question 5.
The trucking company also needs to deliver 1\(\frac{2}{3}\) tons of oak logs and 1\(\frac{7}{12}\) tons of maple logs. Which load weighs more?
Answer:

In the above-given question,
given that,
The trucking company also needs to deliver 1\(\frac{2}{3}\) tons of oak logs and 1\(\frac{7}{12}\) tons of maple logs.
1(2/3) and 1(7/2).
5/3 = 1.6.
9/2 = 4.5.
so the weight of maple logs is more.
Question 6.
In a load of \(\frac{3}{4}\) ton of steel rods, \(\frac{1}{8}\) of them are bent. How many tons of steel rods are bent?
Answer:
The number of tons of steel rods is bent = 0.625.
Explanation:
In the above-given question,
given that,
In a load of \(\frac{3}{4}\) ton of steel rods, \(\frac{1}{8}\) of them are bent.
3/4 and 1/8.
3/4 = 0.75.
1/8 = 0.125.
0.75 – 0.125 = 0.625.
so the number of tons of steel rods is bent = 0.625.
Question 7.
The company delivered 1\(\frac{3}{5}\) tons of bricks to one building site. They delivered 2\(\frac{1}{2}\) times this much to a second site. What was the weight of the load the company delivered to the second site?
Answer:
The weight of the load the company delivered to the second site = 0.9 tons.
Explanation:
In the above-given question,
given that,
The company delivered 1\(\frac{3}{5}\) tons of bricks to one building site.
They delivered 2\(\frac{1}{2}\) times this much to a second site.
1(3/5) and 2(1/2).
8/5 – 5/2.
8/5 = 1.6.
5/2 = 2.5.
2.5 – 1.6 = 0.9.
so the weight of the load the company delivered to the second site = 0.9 tons.
