find the fraction which has the same ratio to 2 / 5 that 3 / 7 has to 6 / 5
"p : 2 / 5 = 3 / 7 : 6 / 5 as the product of the means is equal to the product of the extremes . p * 6 / 5 = 2 / 5 * 3 / 7 p * 6 / 5 = 6 / 35 p = 1 / 7 = > p = 1 / 7 answer : e"
multiply(divide(divide(3, 7), divide(6, 5)), divide(2, 5))
