Question

А В
+ 3 7
6 A how to write this sum​

Answer 1

Answer:

You need to write like this:

Explanation:

AB

+ 37

= /(a+b)=37/40 can be manipulated into:

a=(37/3)b

Therefore,

a/(a-b) = ((37/3)b) / ((37/3)b-b)

If you reduce the right side you get

a/(a-b) = 37/34

I will leave the basic math as an exercise for the reader.
