To determine which equations yield a quotient of 80, let's compute the quotient for each one using mental math.
-
1600 ÷ 20:
- 1600 ÷ 20 = 80. (This is correct)
-
16,000 ÷ 20:
- 16,000 ÷ 20 = 800. (This is not correct)
-
160 ÷ 20:
- 160 ÷ 20 = 8. (This is not correct)
-
16,000 ÷ 200:
- 16,000 ÷ 200 = 80. (This is correct)
-
1600 ÷ 2:
- 1600 ÷ 2 = 800. (This is not correct)
The correct equations that have a quotient of 80 are:
- 1600 ÷ 20
- 16,000 ÷ 200
