if 40 % of a number is equal to two - thirds of another number , what is the ratio of the first number to the second ?
"suppose the first number is x and the second numbery . therefore , 40 % of x = 2 ⁄ 3 of y ∴ x ⁄ y = 2 ⁄ 3 × 100 ⁄ 40 = 5 ⁄ 3 answer d"
divide(divide(const_1, const_4), divide(40, const_100))
