Answer:
There are 251 7s in 1762
Step-by-step explanation:
* Lets explain how to solve the problem
- To find how many 7s in 1762 lets distribute the number by parts
# First we will take the two left digits (17)
∵ 7 × 2 = 14 the nearest number to 17
- Subtract 14 from 17
∵ 17 - 14 = 3 (the remainder)
- Now we will take 3 with the digit 6 ⇒ 36
∵ 7 × 5 = 35 the nearest number to 36
- Subtract 35 from 36
∵ 36 - 35 = 1 (the reminder)
- Take 1 with the digit 2 ⇒ 12
∵ 7 × 1 = 7 the nearest number to 12
- Subtract 7 from 12
∵ 12 - 7 = 5 (The last reminder)
- From all above the quotient is 251 and the remainder is 5
* There are 251 7s in 1762
∵ The quotient is 251 and the remainder is 5
∵ The quotient is the classroom numbers
∴ There are 251 classrooms
∵ The remainder is the number of garbage bags
∴ There are 5 garbage bags
∴ The reminder is 5
* To check the answer lets use the partial product
# 251 × 7
- 7 × 200 = 1400
- 7 × 50 = 350
- 7 × 1 = 7
# Add the answers
∴ 1400 + 350 + 7 = 1757
∵ 1762 - 1757 = 5
∴ 251 × 7 + 5 = 1762
