Find the amount when the base and percent are known
amount = base x percent
convert 1 % to decimal
remove the % symbol. Divide 1 by 100
1 / 100 = 0.01
Multiply 128 times the decimal
128 x 0.01 = 1.28
1.28 is 1 % of 128

1.28
a percent is parts per hundred. Divide by 100 = 1 %
divide by 100 and multiply by 2 = 2 %
OR another way to think of it
multiply by that number of 100ths
x * 3/100 = 3% of x
1/100 * 128 = 1.28

128 divided by 100 = 1.28 (which is your 1%)
:)
So If you wanted to work out say 7%
128 divided by 100 = 1.28
1.28 x 7 = 8.96 (which is your 7%)
Just follow that basic rule and you'll be fine :)

tip
how much is N % out of M = (N/100) * M
how much is 1% out of 128 = (1/100) * 128 =1.28

1 percent means one out of 100. In decimal form, it's 0.01
"of" in word problems means "multiplied by."
So 1% of 128 would be
(1/100)*128
Which is 1.28

1.28.
you just have to move the decimal 2 points to the right because its the same as dividing by 100.
