How many marbles

Question

 David have a 328 Marbles. Matthew and David have 176 Marbles.  Joseph 5 times as many marbles is Matthew. How many marbles does David

Answer 1

I disagree.

 

If David has 328 marbles how can Matthew AND David have less?

If you meant David and Matthew have 328, while David has 176 then: M + D = 328 D = 176 J = 5M Matthew has 328-176 = 152 Joseph has 5 x 152 = 760
