Question

beth drove 45 miles and used 3 3/4 gallons of gas.Martha drove 85 miles and used 5 2/3 gallons of gas.which driver use fewer gallons of gas per mile

Answer 1

Beth

45 ÷ 15/4 gallons

45 * 4/15

3 * 4 = 12 gallons used by Beth

Martha

85 ÷ 17/3

85 * 3/17

5 * 3 = 15 gallons used by Martha

We know that 12 < 15.

So, Beth used fewer gallons of gas per mile.
