We are able to make this easier by turning 25% into the fraction 1/4
1/4 * 162.5
Utilize the equation: a * ( b / c ) = ( ( a * b ) / c )
1 * 162.5 / 4 = 162.5 / 4
If you solve the above you get the quotient of 40.625
The alternative is to multiply 0.25 by 162.5 which will also yield the answer of 40.625
Remember 100% = 1.0, and 25% = 0.25 you can convert between percentages, decimals, and fractions to make solving these problems easier.
Converting to percentage is simply a% = ( a / 100 )
