During a bike challenge, riders have to collect various colored ribbons. Each 1/2 mile they collect a red ribbon, each 1/8 mile they collect a green ribbon, and each 1/4 mile they collect a blue ribbon. Which colors of ribbons will be collected at the 3/4 mile marker?
Plus every fraction you will get 7/8
And the question says about the ribbons he will get at 3/4 miles
so let the whole road is 1
so, according to the equation ; (1-7/8) = 1/8
and (1-1/4) = 3/4
so the answer is green and blue
