If a : b= 5:8 and a = 20, find b.

32

Step-by-step explanation:

a:b = 5:8 means a/b = 5/8

20/b = 5/8

Cross multiplication will give you b = 32

b = 32

Step-by-step explanation:

20/5 = 4

So for finding b, we have to multiply 8 * 4 which is 32.

step-by-step explanation: step 3 should really go to step seven, but anyway never mind.
