if 30 % of a number is equal to one - fourth of another number , what is the ratio of first number to the second number ?
let 30 % of a = 1 / 4 b . then , 30 a / 100 = 1 b / 4 = > 3 a / 10 = 1 b / 4 a / b = ( 1 / 4 * 10 / 3 ) = 5 / 6 a : b = 5 : 6 . answer : e
divide(divide(const_1, const_4), divide(30, const_100))
