If a/b = 1/3, then 3a + 2b/3a - 2a - 2b is equal to?
If a/b = 1/3, then 3a + 2b/3a - 2a - 2b is equal to?
Explanation
Given expression = (3a + 2b) / (3a - 2b)
= [3(a/b) + 2] / [3(a/b) - 2]
= [3 x 1/3 + 2] / [3 x 1/3 - 2]
= 3 / -1
=-3
Given expression = (3a + 2b) / (3a - 2b)
= [3(a/b) + 2] / [3(a/b) - 2]
= [3 x 1/3 + 2] / [3 x 1/3 - 2]
= 3 / -1
