Question 729661: if a fractions value is 3/5 if the numerator and denominator are both increased by 3 the resulting fraction equals 5/8. What is the original fraction? What is the proper way to solve this question? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! LET N BE THE MULTIPLIER.
(3N+3)/(5N+3)=5/8 CROSS MULTIPLY
8(3N+3)=5(5N+3)
24N+24=25N+15
24N-25N=15-24
-N=-9
N=9 ANS. FOR THE MULTIPLIER.
PROOF:
(3*9+3)/(5*9+3)=5/8
(27+3)/(45+3)=5/8
30/48=5/8 REDUCE THE LEFT FRACTION.
5/8=5/8
