Multiply interior's height x width x depth. Ex: lets say 10 inches x 12 inches x 8 inches = 10 x 12 = 120 x 8 = 960. Divide 960 by 1728 (12 x 12 x 12) =. 56 cubic ft( point 56) just a tad more then half cubic ft.
Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
Calculate the factor (f) for making the decimal number an integer:
f = 10 to power d
Example: f = 10 power 2 = 100
Multiply and divide the decimal number x by the factor f:
x * f / f = y / f
Example:
2.56 * 100 / 100 = 256 / 100
Find the greatest common divisor (gcd) of the fraction.
Example:
gcd(256,100) = 4
Reduce the fraction by dividing the numerator and denominator by the gcd value:
Example:
256 / 100 = (256/4) / (100/4) = 64/25
Example
One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25
Ratios are usually written as xx/1 such as 8 to 1 or 4 to 1 so that one is the base number. If you have 8 black sheep out of 64 then it's ration is 64/8 but you want to reduce the 8 to 1 so divide 8 by 8=1. now you have to do the same thing to the the other side of the equation so you have to divide 64 by 8 = 8 or to simplify this divide the first number by the last = the radio. Thus 64/8 = 8/1 on a more difficult scale let's do 6888/123 is 6888 divided by 123 or 56 to 1
