Question

Emanuel was charged $32 for a 14 2/9km taxi ride What was the cost per kilometer?

Answer 1

Answer: 1km = 2.25$

Explanation:
32 = 14 2/9
32 = 128/9 (make it into fraction by taking 14 x 9 + 2)

32 divide by 128/9 = 128/9 divide by 128/9 (divide both sides by 128/9)

32 x 9/128 = 128/9 x 9/128
9/4 = 1
2.25$ = 1km
