The hardest part is converting this from words into an equation:
"What percentage" --> n/100
"of" --> x
"125" --> 125
"is" --> =
"25" --> 25
The equation is therefore:
n
------ x 125 = 25
100
Divide both sides by 125:
n ......... 25
------ = ------
100 ... 125
Multiply both sides by 100:
....... 25
n = ------ x 100
...... 125
You can reduce this to:
n = 1/5 x 100
n = 100 / 5
n = 20
So the answer is 20%
Now you know the long way, you would just do:
25 / 125 x 100 --> 20%

20%
Algebraically: 25/125=x/100
crossmultiply to get 250=125x
Divide by 125, so x=20
OR
On calculator= 100 divided by 125, times 25
(Works out to 20)
