Let’s solve each problem one by one.
We’re finding the
unit rate — that means we want to know how much of something happens
per 1 unit (like per hour, per book, per row, etc.).
To find the unit rate, divide the total amount by the number of units.
---
1. 360 kilometers per 6 hours
→ Divide: 360 ÷ 6 =
60 km per hour
2. $72 for 8 books
→ Divide: 72 ÷ 8 =
$9 per book
3. 600 seats in 15 rows
→ Divide: 600 ÷ 15 =
40 seats per row
4. 168 boys in 8 groups
→ Divide: 168 ÷ 8 =
21 boys per group
5. 14 eggs every 56 days
→ Divide: 14 ÷ 56 =
0.25 eggs per day
*(or you can say 1 egg every 4 days — but since it asks for unit rate per day, 0.25 is correct)*
6. 198 calls per 9 hours
→ Divide: 198 ÷ 9 =
22 calls per hour
7. 480 pages per 4 days
→ Divide: 480 ÷ 4 =
120 pages per day
8. 100 miles on 5 gallons of gas
→ Divide: 100 ÷ 5 =
20 miles per gallon
9. $70 for 10 comic books
→ Divide: 70 ÷ 10 =
$7 per comic book
10. $240 for 12 hours of work
→ Divide: 240 ÷ 12 =
$20 per hour
11. 54 goals in 27 games
→ Divide: 54 ÷ 27 =
2 goals per game
12. 160 mistakes every 8 tests
→ Divide: 160 ÷ 8 =
20 mistakes per test
13. 900 centimeters in 2 minutes
→ Divide: 900 ÷ 2 =
450 cm per minute
14. 420 points in 6 games
→ Divide: 420 ÷ 6 =
70 points per game
