Question

The denominator of a fraction is greater than the numarator by 4.if both the denominator and numerator is increased by 5,the new fraction is 2/3.find the original fraction​

Answer 1

Answer:

I think 4/7 is the answer...The numerator is x so denominator is x+3

So after adding 7 it will be

x+7/x+3=x/x+3+1

x+7/x+3=x+x+3/x+3

x+7/x+3=2x+3/x+3

Since denominators are same. The numerators can be easily compared...

x+7=2x+3

x-2x=3-7

x=4

So Numerator is 4 and denominator is 7
