Question

Use mental math to find equations that have a quotient of 80. Select all that apply.

1600 divide by 20
16,000 divide by 20
160 divide by 20
16,000 divide by 200
1600 divide by 2

Answer 1

To determine which equations have a quotient of 80, we can evaluate each option using mental math.

1. **1600 divided by 20**:
\( 1600 \div 20 = 80 \)
(This is correct.)

2. **16,000 divided by 20**:
\( 16,000 \div 20 = 800 \)
(This is not correct.)

3. **160 divided by 20**:
\( 160 \div 20 = 8 \)
(This is not correct.)

4. **16,000 divided by 200**:
\( 16,000 \div 200 = 80 \)
(This is correct.)

5. **1600 divided by 2**:
\( 1600 \div 2 = 800 \)
(This is not correct.)

The equations that have a quotient of 80 are:
- **1600 divided by 20**
- **16,000 divided by 200**
