You can solve this by taking 12/21 and multiplying by 100. So, 12/21 = .571 * 100 = 57.1%
21/2 = 250%
It is: (35-21)/35 times 100 = 40% decrease
(12/5 x 100) - 100 = 140 percent. The percentage change between 5 and 12 is a 140 percent increase.
50% = 0.50 = 1/21/2 of 12 = 6
an increase of 75%
(21/x) (12/100)= 175
You can solve this by taking 12/21 and multiplying by 100. So, 12/21 = .571 * 100 = 57.1%
21 = (.12)(x) 21 / .12 = x Answer: 175
