3 / 8 = w / w + 2

3 over 8 equals w over w + 2

3 w

_ = _

8 w+2

What is w? My answer is w = 1.2 but I'm not sure.

132 / 35 = 12 / a + 1

132 over 35 equals 12 over a + 1

35(12) = 132(a+1)

430 = 132a + 132

Do you mind telling me how to get a? Can I subtract 132 from both sides then divide by 132a? - September 29th 2012, 11:38 AMMarkFLRe: What would be w? Proportions question
You should have:

420 = 132a + 132

You are almost right...subtract 132 from both sides then divide by 132, this will isolate*a*and give you its value. - September 29th 2012, 11:42 AMRuneRe: What would be w? Proportions question
298 = 132a

Now I divide 298 by 132a (132a by 132) and I get this.

2.257575757575758 = a

Is there anyway to make this into a fraction instead? - September 29th 2012, 11:53 AMMarkFLRe: What would be w? Proportions question
