Answer:
17%
Step-by-step explanation:
to find the percentage of something, you have to fill out the following formula:
x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:
125x = 2125
then you have to divide, to single out x:
the answer is 17
so it is 17%
6350
500×12.7=6350
so all you do is take 500×12.7 multiply it an you will get the answer 6350
x = -1
-3 +12 = 9
-9x = 9
-9(-1)=9
9 - 12 = -3
