McGraw-Hill Math Grade 3 Answer Key Chapter 10 Lesson 2 Reading a Picture Graph
Solve
Use the picture graph to answer the questions.
Question 1.
Who practices 14 hours each month?
Answer:
Each single ball = 4 hours
Half ball = 2 hours
From the above picture graph, we can observe that Ines practices 14 hours each month as there are 3 full balls and 1 half ball.
3 × 4 = 12 hours
1/2 × 4 = 2 hours
12 + 2 – 14
Question 2.
How many fewer hours each month does Logan practice than lines?
Answer:
Ines practiced for 14 hours
Logan practices for 10 hours as there are 2 full balls and 1 half ball.
2 × 4 = 8
1/2 × 4 = 2
8 + 2 = 10 hours
We need to find how many fewer hours each month Logan practices than lines.
14 – 10 = 4 hours
Therefore Logan practices 4 fewer hours than Ines.
Question 3.
Who practices more than 8 hours but less than 12 hours?
Answer:
Logan practices for 10 hours as there are 2 full balls and 1 half ball.
2 × 4 = 8
1/2 × 4 = 2
8 + 2 = 10 hours
Thus Logan practices for more than 8 hours but less than 12 hours.
