Math in My World
Example 1
Anita’s family went on vacation to an amusement park. The park has 5 entrances. 1,500 people entered the park and separated into equal lines. How many people are in each line?
McGraw Hill My Math Grade 4 Chapter 5 Lesson 1 Answer Key Divide Multiples of 10, 100, and 1,000 1
Divide 1,500 people into 5 equal groups.
One Way Use a multiplication pattern.
5 × 3 = 15 → 15 ÷ 5 = 3
5 × 30 = 150 → 150 ÷ 5 = 30
5 × 300 = 1,500 → 1,500 ÷ 5 = ____
Answer:
There are 300 people in each line.

Another Way Use a basic fact and place value.
15 ÷ 5 = 3 ← basic fact
150 ÷ 5 = 30 ← 150 is 10 times as big as 15. So, the quotient 30, is 10 times as big as 3.
1,500 ÷ 5 = ____ ← 1,500 is 100 times as big as 15. So, the quotient is 100 times as big as 3.
So, there are ____ people in each line.
Answer:
There are 300 people in each line.

Explanation:
15 ÷ 5 = 3 ← basic fact
150 ÷ 5 = 30 ← 150 is 10 times as big as 15. So, the quotient 30, is 10 times as big as 3.
1,500 ÷ 5 = 300 ← 1,500 is 100 times as big as 15. So, the quotient is 100 times as big as 3.
So, there are 300 people in each line.

Example 2
Find the quotient of 2,400 and 4.
Find 2,400 ÷ 4.
One Way Use a multiplication pattern.
4 × 6 = 24 → 24 ÷ 4 = 6
4 × 60 = 240 → 240 ÷ 4 = 60
4 × 600 = 2,400 → 2,400 ÷ 4 = _____
Answer:
600
Another Way Use a basic fact and place value.
24 ÷ 4 = 6 ← basic fact
240 ÷ 4 = 60 ← 240 = 10 × 24. So, 60 = 10 × 6.
2,400 ÷ 4 = _____ ← 2,400 = 100 × 24. So, the quotient is 100 times as big as 6.
So, 2,400 ÷ 4 = _____
Answer:
600

Explanation:
24 ÷ 4 = 6 ← basic fact
240 ÷ 4 = 60 ← 240 = 10 × 24. So, 60 = 10 × 6.
2,400 ÷ 4 = 600 ← 2,400 = 100 × 24. So, the quotient is 100 times as big as 6.
So, 2,400 ÷ 4 = 600
