1 answer

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
