# If (4m + 3n)/(4m - 3n) = 7/4 Use Properties of Proportion to Find M : N - ICSE Class 10 - Mathematics

#### Question

If (4m + 3n)/(4m - 3n) = 7/4 use properties of proportion to find m : n

#### Solution

Given (4m + 3n)/(4m - 3n) = 7/4

Applying componendo and dividendo

(4m + 3n + 4m - 3n)/(4m + 3n - 4m + 3n) = (7 + 4)/(7 - 4)

(8m)/(6n) = 11/3

m/n = 11/4

Is there an error in this question or solution?
