If a/b=3/4 and a/c=5 what is b/c?

i will mark brainliest

b/c = 20/3

Step-by-step explanation:

a/b =3/4

a/c = 5

a/c =5

Divide both sides by a/b

a/c ÷a/b = 5÷a/b

Replace the a/b on the right by 3/4 since they are equal

a/c ÷a/b = 5÷3/4

We will use copy dot flip

a/c * b/a  = 5 * 4/3

b/c = 20/3

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

6e14 is the answer.
