What strategies can you use to divide by 10?

There are 50 students going on a field trip to the Philadelphia Zoo. The students are separated into equal groups of 10 students each. How many groups of students are there?

• What do you need to find?
Answer: We need to find the number of groups of students is present.

• Circle the numbers you need to use.
Answer: 5

Explanation:
The total number of students going on a field trip=50

How is counting on a number line to divide by 10 different from counting on a number line to multiply by 10?

Other Ways

A. Use a number line.

• Start at 50 and count back by 10s until you reach 0.
• Count the number of times you jumped back 10.

You jumped back by 10 five times.
50 ÷ 10 = _5__

B. Use a multiplication table.
Divide. 50 ÷ 10 = __5_
Since division is the opposite of multiplication, you can use a multiplication table to find a quotient.
Think of a related multiplication fact.
_5_ × 10 = 50

Step 1
Find the factor, 10, in the top row.

Step 2

Question 1.
Use repeated subtraction to find 30 ÷ 1o. ____

Answer: 3
{we subtracted 10, three times to get 0}
Explanation:
30/10=3.
A. multiplication.
Since division is the opposite of multiplication, you can use a multiplication table to find a quotient.
Think of a related multiplication fact.
3*10=30.
B. Use a number line.

• Start at 30 and count back by 10s until you reach 0.
• Count the number of times you jumped back 10.

You jumped back by 10 three times.
30/10=3

Find the unknown factor and quotient.

Question 2.
10 × ___ = 40 ___ = 40 ÷ 10
Answer:

(A) 4
(B) 10
(C) 14
(D) 40
Answer: Option A is correct

Explanation:
Number of days Ava smells dog shampoos=10
