To find the base when the percentage and rate per cent are given: Divide the percentage by the numerator of the rate per cent, and multiply the quotient by 100. Note. Since 750 divided by 25 and multiplied by 100 equals 750 divided by 0.25 (which is the rate per cent), the form of written work given below may be used instead of that above: Written WORK.-= 3000.
