(4m+5):(3m+7)=13:17
(4m+5)/(3m+7)=13/17
17×(4m+5)=13×(3m+7)
(17×4m)+(17×5)=(13×3m)+(13×7)
68m+85=39m+91
68m-39m=91-85
29m=6
m=6/29
Answer=6/29
solution:-
L-H-S
we can also write this
4m + 5 / 3m + 7
R-H-S
13 : 17
13/17
Compare LHS and RHS
13/17 = 4m + 5 / 3m + 7
13(3m + 7) = 17(4m + 5)
39m + 91 = 68m + 85
68m - 39m = 91 - 85
29m = 6
m = 6/29 Ans
