25/100 =x/100 would that be 60% when the problem is solved?

Question

mathteacher1729 · Answer

Are you sure you copied the problem correctly?

$$\frac{25}{100} = \frac{x}{100}$$

The denominators are the same (they are both 100) so the numerators must be the same... that means x = 25.

The orginal question is what percent of 25 is 15?

anonymous · Answer

25/15 x/100

bahrom7893 · Answer

Set up a proportion:
25 - 100%
15 -  x%
x = (15*100)/25

bahrom7893 · Answer

x = 60

bahrom7893 · Answer

x = 60% I meant

mathteacher1729 · Answer

Percentage is always "something over 100"

4/100 = 4 %

35/100 = 35 %  and so on.

So asking "what percentage of 25 is 15" is really asking:

$$\frac{15}{25}=\frac{x}{100}$$

From here you can cross multiply just like Bahrom did and have:

$$x=\frac{15*100}{25}$$

There is lots of canceling here, and you get x = 60, which means 60% in this case. :)
