It is: (28/40)*100 = 70%
percentage = 40%% rate:= 28/70 * 100%= 0.40 * 100%= 40%
28/70 = 2/5 = 40%
seventy 28/40 x 100 = 2,800/40 = 280/4 = 70/1 = 70
28/40 = 0.7, so when you convert 0.7 to a percentage, you get 70%.
5%
This is a 40% decrease.
Since the quiz/test (or whatever it may be) is out of '40' we know that 40 out of 40 is 100%, or the full marks. Now, since we know that, we can divide 28 by 40. 28/40 = 0.7 After, we take this number and multiply it by 100 to make it equal to the percentage.. 0.7 x 100 = 70 So, 28 out of 40 is equal to 70%
It is: (45-40)/40 times 100 = 12.5% increase
28% of 40= 28% * 40= 0.28 * 40= 11.2
Repeated proportional change is when you take a percentage of a number (e.g. 80% of 50) and multiply it by a percentage. E.g. 40 is 80% of 50 50 is X% of 40 Find X 40 / 0.8 = 50 50 / 40 = 1.25 1.25 * 100 = 125% X = 125
To find 40 percent of a number, multiply the number by 0.4. In this instance, 0.4 x 70 = 28. Therefore, 40 percent of 70 is equal to 28.
