in a certain school, the ratio of boys to girls is 5 to 13. if there are 160 more girls than boys, how many boys are there?
subtract(divide(160, subtract(const_1, divide(5, 13))), 160)
"the ratio of b to g is 5 : 13 and the other data point is g are more than boys by 160 . . . looking at the ratio we can say that the 8 ( 13 - 5 ) extra parts caused this diff of 160 . so 1 part corresponds to 160 / 8 = 20 and so 5 parts correspond to 5 * 10 = 100 . a"
