wheel of a bicycle rotates 512 times with 1 113 rotations of

wheel of a bicycle rotates 5(1/2) times with 1 (1/13) rotations of the pedals.write the ratio of back wheel rotations to pedal rotations in simplest form

We put the numbers into improper fractions (11/2 and 14/13) and then reduce by dividing 11/2 by 14/13, to get ratio of back wheeel rotation =

(11*13)/28

or 143/28 back wheel rotations to pedal rotations
