what is 3 2 / 3 - 2 1 / 4 divided by 6 / 7 - 2 / 5 ?
"3 2 / 3 - 2 1 / 4 = 11 / 3 - 9 / 4 = ( 44 - 27 ) / 12 = 17 / 12 6 / 7 - 2 / 5 = ( 30 - 14 ) / 35 = 16 / 35 so 17 / 12 / 16 / 3 = 17 / 12 * 3 / 16 = 17 / 64 answer - c"
subtract(divide(add(multiply(const_10, 3), 3), 3), divide(add(const_10, 2), 4))
