a leaf blower runs on a mixture of gas and oil. the ratio of the ounces of gas to the ounces of oil is 40 to 1.

Question

how many ounces of gas does the leaf blower need for 2 ounces of oil?

Answer 1

Since the ratio of gas to oil is 40:1, for every 40 ounces of gas, there is 1 ounce of oil.

To determine how many ounces of gas is needed for 2 ounces of oil, we need to set up a proportion:
40 / 1 = x / 2

Cross multiplying:
1 * x = 40 * 2
x = 80

Therefore, the leaf blower would need 80 ounces of gas for 2 ounces of oil.
