Two ways:
= 
and 1/4 = 25%
Another way.
300 = n% of 1200
Problem - we can't move n% back two place to change it to a decimal since we don't know what n is. Solution - move the decimal back on the 1200 two places because since of means x, it doesn't matter. Sample .45 x 32 = 45 x .32 Notice that the decimal can be place on either number and it results in the same answer.
So 300 = 12n (1200 moved back 2 places)
now divide by 12
<u>300</u> = <u>12n
</u>12 12 and once again n=25(%)<u>
