Question

the ratio of students with bikes to students with scooters in the school is 85:51. What is the greatest common factor that you could use to simplify this ratio

Answer 1

Answer:GCF=17

To find the greatest common factor, or GCF, of the numbers, we first need to list the prime factors of both 85 and 51

52=3*17

85=5*17

17 is the sole common factor that these two numbers have in common, therefore 17 is the GCF.

To simplify the ratio, simply divide both numbers by 17.

85:51 becomes 5:3

Answer 2

The greatest common factor is 17
