1/2 + 1/14 = 4/7

The only integer solutions are {m=2, n=14} or {m=14, n=2}. Counting both permutations, there are 2 solutions.

N=4, M=7.

Well 4 divided by 7 = .57 so...ok leave me alone I'm only in fifth grade! Lol

I am the best in maths :-see the solution

1/m+1/n=4/7

n+m/mn=4/7

n+m/mn=4/7

then cross multiply.

7n+7m=4mn

7(n+m)/4mn.final ans

1/m+1/n=4/7

n+m/mn=4/7

n+m/mn=4/7

then cross multiply.

7n+7m=4mn

7(n+m)/4mn.final ans

1/m + 1/n = 4/7 SO: Invert the whole problem and: M/1 + n/1 = 7/4 or m + n = 7/4
