By what percent will a fraction increase if its numerator is decreased by 30%
1 answer:
Answer:
40%
Step-by-step explanation:
Let x = numerator
Let y = denominator
Decreased by 30% = 100% - 30% = 70% = 70/100 = 0.7
Decreased by 50% = 100% - 50% = 50% = 50/100 = 0.5
1.4 as a percentage = 1.4 x 100 = 140%
Therefore, the percentage increase is 140 - 100 = 40%
