What is the percent increase from \(\frac{1}{5}\) to \(3 \frac{3}{4}\)?
A. 17.75%
B. 35.5%
C. 177.5%
D. 1775%
E. 3550%
We use the percent increase formula, (new - old)/old x 100, obtaining:
(15/4 - 1/5)/(1/5) x 100
(75/20 - 4/20)/(1/5) x 100
(71/20)/(1/5) x 100
(71 x 5)/20 x 100
71/4 x 100
71 x 25 = 1,175%
Answer: D
