Question

a truck fills 3/4 of gas, and uses 1/3 of gas to travel from Town A to Town B. The total capacity of the tank is 70 gallons. How much gas has used by the truck?

Answer 1

29 1/6 OR 29.1666..

Explanation:

70/2=35

35 = 1/2

35/2=17.5

This means that 1/4 = 17.5.

17.5x3, (35 + 17.5) =52.5.

3/4 = 52.5

3/4 - 1/3

Multiply diagonally 3x3=9

1x4=4

9-4=5

5/?

Multiply denominators

4x3=12

3/4-1/3=5/12

5/12 x Full Tank (70/1)

Frankly I'd rather skip showing you how to multiply fractions so lets just skip that (I'll explain it if you ask)

175/6

Break it down

6x29=174

180-174=6

29
