    You must be careful with these kind of problems: because it increases from 125 to 130, you'll have to compare the increase of 5 with the original number (125). So 125 stands for 100%. Some find this formula handy: \[change=\frac{ new-old }{ old }\cdot100\%\]

    Always convert a fraction to a pecentage by multiplying with 100

    Do the opposite: divide by 100, getting\[\frac{ 65 }{ 100 }\]then simplify...

    If 159 is 30% of a number and you want to know what that number is: Divide 159 by 30 to get 1%. Then multiply by 100.

    ok Jackets are on sale for 25% off. If the original price of a jacket is $120, what is the sale price? how would I do this

    So $120 stands for 100%. If there is 25% off, the price goes down with a quarter, which is $30. New price: $90. Another way of doing this: look at what will be left: 25% off means: there is only 75% left, or three quarters (0.75). So 0.75*120=90. New price is $90.
