Percent means out of 100 so 50% means 50 out of 100 or 50/100. This simplifies to ½. Since "of" means multiply we can multiply by ½ or divide by its reciprocal which is 2.
50% of 240 = 240 x ½ = 240 ÷ 2 = Since 200% equals 2, the easy way to find 200% is to multiply by 2. Another way is 100% equals the number. 200% is twice as much so double it.
200% of 240 = To find 10%, we can move the decimal one place left
because 10% equals 0.1 in decimal form or
in fraction form.
10% of 240 = 240 x 0.1 =
Because 20% is twice as much as 10%, we can find
10% and it. We may also divide by 5 as it is
the reciprocal of the fraction which also equals
20%.
20% of 240 = Since 5% is one-half of 10%, to find 5%, find 10% first
and then divide by . Another way to find 5% is
to multiply by 0.05 which is 5% in decimal form or
divide by 20 the reciprocal of 1/20, the fraction that
equals 5%. 5% of 240 is . Since 1% equals 0.01, move the decimal places
left to find 1%. 1% of 240 is . 25% equals 0.25 which equals 25/100 which simplifies
to . We can multiply by its decimal form or
fraction form or divide by it reciprocal (which is 4).
25% of 240 = 240 x 0.25 = 240 x ¼ = 240 ÷ 4 = Since 75% is three times as large as 25%, to find 75%
find 25% first and multiply it by .
75% of 240 = 25% of 240 times 3 = 33⅓% equals 0.333... which equals ⅓. So if we
know what fraction it equals and its reciprocal (3),
we can divide by the reciprocal to find 33⅓%.
240 x 33⅓% = 240 x ⅓ = 240 ÷ 3 = Since 66⅔% is twice as large as 33⅓%, just find 33⅓%
first and double it. 66⅔% of 240 is . Since 1% is 240 is 2.4, we can find 2% by doubling it.
