Question

Mark's car used a full tank of gas on a recent trip. Jill's economy car used only 3/4 of the amount of gas that Mark used on the same trip. How many times more gas did Mark use than Jill?

a) 4 times
b) 3 times
c) 2 times
d) 1.33 times

Answer 1

Mark used 1.33 times more gas than Jill. We found this by dividing the full tank Mark used (represented as 1) by the 3/4 tank Jill used, resulting in an answer of 4/3, or approximately 1.33.

Step-by-step explanation:

The question is asking how many times more gas Mark used compared to Jill. If Mark used a full tank and Jill used only 3/4 of that amount, it means Jill used less gas. The amount Mark used can be represented as 1 (whole or full tank), while Jill used 3/4 of Mark's consumption. To find out how many times more gas Mark used compared to Jill, we divide the amount Mark used by the amount Jill used:

Mark's usage / Jill's usage = 1 / (3/4)

To solve this division problem involving fractions, we multiply by the reciprocal of the divisor, which is:

1 × (4/3) = 4/3

This calculation shows that Mark used 1.33 times more gas than Jill did on the same trip. Thus, the correct answer is d) 1.33 times.
