Well 20 goes into 100, 5 times.... so if you multiply the number out of 20(in this case, 15) by 5 you get you percentage.
Or you could just multiply 15/20(fraction) by 5.
15/20x5= 75% 20x5=100... so 15x5= 75% :)
its really simple.
Alternatively just do 15/20 and times by 100. Essentially that is what has happened above but that method is unnecessarily complicated for larger numbers if you don't know their factors/multiples.
75
% rate = 20% = 15/175 * 100% = 0.2 * 100% = 20%
3 is what percent of 15= 3 / 15= 0.2Converting decimal to a percentage: 0.2 * 100 = 20%
% rate= 3/20 * 100%= 0.15 * 100%= 15%
If you have 20 oranges and 3 are bad then the percentage of bad apples is 15.
percentage of 15 = 1500%15 * 100% = 1500%
3/15 as a percentage is 20%
15/20 * 100 = 75% =====
percentage = 15% % rate: = 3/20 * 100% = 0.15 * 100% = 15%
Increase = 15 dollars. 15 dollars, as a percentage of 20 dollars = 15/20 * 100 = 75%
It is: 15/20 times 100 = 75%
percentage = 75%% rate:= 15/20 * 100%= 0.75 * 100%= 75%
Three is 20% of 15.
15 is 75% of 20.
3/20 = 15%
15%.
3/20 as a percentage is 15%
3/20 = 15%
