I will do 3.75-0.2= 3.55 ; % difference is 3.55/0.2 * 100 = 1775 (D).

Any percentage change is {(New-Old)/Old} multiplied by 100

Easy to solve then.

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%
