Answer:
8 times
Step-by-step explanation:
2 x 8 = 16
64 + 16 = 80
10 x 8 = 80
9/19 = x / 152....9 oz oil to 19 gallons gas = x oz oil to 152 gallons gas
cross multiply because this is a proportion
(19)(x) = (152)(9)
19x = 1368
x = 1368/19
x = 72 oz of oil <==
Do you mean checking your work? In that case it would be 9*20.
Subtracting whole numbers does not include subtracting negative numbers, whereas when subtracting integers you can include negative numbers.
