Problem: if the given two numbers are respectively 7 % and 28 % of a third number , then what percentage is the first of the second ?
Rationale: "here , l = 7 and m = 28 therefore , first number = l / m x 100 % of second number = 7 / 28 x 100 % of second number = 25 % of second number answer : b"
annotated_formula: multiply(divide(divide(7, const_100), divide(28, const_100)), const_100)
