$ 700 is divided amongst a , b and c so that a may get 2 / 3 as much as b and c together , b may get 6 / 9 as much as a and c together , then the share of a is
a : ( b + c ) = 2 : 3 a ' s share = 700 * 2 / 5 = $ 280 answer is d
multiply(divide(700, add(divide(const_2, const_3), const_1)), divide(const_2, const_3))
