a paint store mixes 3 / 4 pint of red paint and 2 / 3 pint of white paint to make a new paint color called perfect pink . how many pints of red paint would be needed to make 36 pints of perfect pink paint ?
"3 / 4 pint is required to make 3 / 4 + 2 / 3 = 17 / 12 pint of perfect pink so 17 / 12 pint requires 3 / 4 pint of red . . 1 pint will require 3 / 4 * 12 / 17 = 9 / 17 . . 36 pints will require 9 / 17 * 36 = 19 pints . . c"
multiply(36, divide(multiply(3, 2), multiply(4, 3)))
