How do you find x% of y?

Calculator method:

Change the percentage to a decimal and then multiply by the amount.

For instance,

40% of 2500

40% as a decimal is 0.4

0.4 x 2500 = 1000

Therefore, 40% of 2500 is 1000

---------------------------------

Non-calculator method:

Find 10% and work from there.

For instance,

10% = 250

40% = 4 x 10% = 4 x 250 = 1000

Therefore, 40% of 2500 is 1000

x% of y would be (x/100)*y.

e.g. 150% of 6 = (150/100)*6 = 9

Convert the x% into a decimal by dividing by 100.

Then multiply y by this decimal either using a calculator or using your preferred method of multiplication.
