Answer (3)

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

Red ribbons: 1
Green ribbons: 6
Blue ribbons: 3 ;

At the 4 3 ​ mile marker, riders will have collected a red ribbon, a green ribbon, and a blue ribbon. Each ribbon is collected based on specific distance intervals that have been met. Therefore, all three colors of ribbons will be collected at this point.
