I have a question here.
If m>0 and x is m% of y, in term of m, y is what % of x
1) 100m
2) 1/100m
3) 1/m
4) 10/m
5) 1000/m

guess you made a mistake in the first answers. the correct one should be 10 000/m

The answer is 10,000/m. You can solve this by plugging in or by using algebra. First, plugging in:

x=m% * y. Let's say x = 100, m = 50, and y = 200. Therefore, 100 = 50% * 200.

200 = 200% * 100. So, y = 200% * x.

Now, we just plug the value of m=50 into the answer choices until we get an answer of 200 (which should be 10 000/m, but for some reason you don't have this answer above).

Algebra:

Remember the general rule that to convert any number into a percent you have to multiply it by 100 (i.e. to covert 2.57 into a percent, you have to multiply 2.57 by 100 to get 257%). Also, to covert a percent into a number you have to divide by 100 (i.e. to covert 257% into a number, you have to divide 257 by 100 to get 2.57).

x=m% * y. Converting m% into a number you get x = (m/100) * y.

Cross multiply to get y = (100/m) * x. To convert 100/m into a percent, multiply by 100 to get 100/m = (100 * 100 / m)% or (10,000/m)%.
