Question

Find the percent of change. Round to the nearest tenth of a percent if necessary. 5/4 to 3/8

Answer 1

5/4 = 1.25
3/8 = 0.375

1.25 - 0.375 = 0.875

0.875/1.25 x 100 = 70%

answer: decrease 70%

Answer 2

5/4 - 3/8 = 10/8 - 3/8 = 7/8

% change = (7/8 / 3/8) * 100 =  (7/3) * 100 = 700/3 = 233.3  %
