Answer:

4/11

Step-by-step explanation:

let the original fraction be x/y

so y=x+7----i

x+4/y-8 = 8/3

from equation i

x+4/x+7-8 = 8/3

x+4/x-1 = 8/3

3x +12 = 8x - 8

-5x = -20

x = 4

putting the value of x in equation i

therefore, y=4+7

y=11

Hence the original rational number is 4/11

I think this should be the correct answer..

Answer:

ok

Step-by-step explanation:

the denominator of a rational number is greater than its numerator by 7.if the numerator is increased by 4 and the denominator is decreased by 8,the new rational number is 8/3. find the original rational number?
