Question

If a-3b=9b-7a then what is the ratio of a to b?

Answer 1

start by using algebra to get all the a's on one side and all the b's on the other

Answer 2

a-3b = 9b-7a
8a = 12b

Answer 3

Then do the next step to transform 8a = 12b into an equation with the ratio (a/b) on the left... what will the number on the right side be?

Answer 4

Would it be 8a/b = 12b

Answer 5

not 12 b just 12 i mean

Answer 6

you need to divide both sides by 8 to get rid of the 8 on the left side...

8(a/b) = 12
(a/b) = 12/8

then you should probably reduce that fraction...
