Estimating Quotients worksheet with four division problems to solve using the same divisor.

Let's solve each problem on the worksheet "Estimating Quotients" step by step. The goal is to estimate the quotient by using compatible numbers (numbers that are close to the actual dividend and easily divisible by the divisor). We’ll follow the instructions: list three division statements with the same divisor, find which dividend is closest to the original, and then estimate the quotient.

Problem 1: 15 ÷ 7 = ?

We need to list three division statements using the same divisor (7):

- 7 ÷ 7 = 1
- 14 ÷ 7 = 2
- 21 ÷ 7 = 3

Now, determine which dividend is closest to 15:

- 14 is closer to 15 than 7 or 21.

So, 15 ÷ 7 is about 2.

✔ Answer: 15 ÷ 7 ≈ 2

Problem 2: 28 ÷ 5 = ?

List three division statements with divisor 5:

- 5 ÷ 5 = 1
- 10 ÷ 5 = 2
- 15 ÷ 5 = 3

But we want dividends near 28, so let’s pick better ones:

Better choices:
- 25 ÷ 5 = 5
- 30 ÷ 5 = 6
- 35 ÷ 5 = 7

Wait — the worksheet says “list three division statements using the same divisor,” but it doesn’t specify the range. Let’s use multiples of 5 around 28:

- 25 ÷ 5 = 5
- 30 ÷ 5 = 6
- 35 ÷ 5 = 7

Which dividend is closest to 28?

→ 25 is closest (since 25 < 28 < 30, and 28 - 25 = 3, while 30 - 28 = 2 → actually 30 is closer!)

Wait! Let’s check:

- 28 - 25 = 3
- 30 - 28 = 2 → So 30 is closer.

So the closest dividend is 30.

Therefore, 28 ÷ 5 is about 6 (since 30 ÷ 5 = 6).

✔ Answer: 28 ÷ 5 ≈ 6

Problem 3: 43 ÷ 8 = ?

List three division statements using divisor 8:

- 40 ÷ 8 = 5
- 48 ÷ 8 = 6
- 32 ÷ 8 = 4

We can write:

- 32 ÷ 8 = 4
- 40 ÷ 8 = 5
- 48 ÷ 8 = 6

Which dividend is closest to 43?

- 43 - 40 = 3
- 48 - 43 = 5 → So 40 is closer.

So, 43 ÷ 8 is about 5

✔ Answer: 43 ÷ 8 ≈ 5

Problem 4: 56 ÷ 9 = ?

List three division statements using divisor 9:

- 45 ÷ 9 = 5
- 54 ÷ 9 = 6
- 63 ÷ 9 = 7

Which dividend is closest to 56?

- 56 - 54 = 2
- 63 - 56 = 7 → So 54 is closer.

So, 56 ÷ 9 is about 6

✔ Answer: 56 ÷ 9 ≈ 6

✔ Final Answers:

1. 15 ÷ 7 ≈ 2
2. 28 ÷ 5 ≈ 6
3. 43 ÷ 8 ≈ 5
4. 56 ÷ 9 ≈ 6

🔍 Explanation Summary:

To estimate quotients, we:

1. Use multiples of the divisor that are close to the dividend.
2. Find which multiple is closest to the original dividend.
3. Use that to estimate the quotient.

This method helps students develop number sense and mental math skills without needing exact division.
