The denominator of a fraction is greater than the numerator by 8. If the numerator is increased by 17 and denominator is decreased by 1, the number obtained is 3/2. Find the fraction.
13/21
x/(x+8) (x+17)/(x+8-1)=3/2 --> x=13 ---> x/(x+8)=13/21
The denominator of a fraction decreases the numerator by 6 and if 8 be added to both the fraction becomes 9/7. Find the fraction.
The denominator of a rational number is greater than its numerator by 10. If the numerator is increased by 5 and denominator is decreased by 1, then the number obtained is 3/4. Find the original rational number.
In a rational number, twice the numerator is 2 more than the denominator. If 3 is added to each i.e. the numerator and the denominator, the new fraction is 2/3.
