Answer:

Daniel has 390 marbles.

Step-by-step explanation:

W = 195

2/5D = 4/5W

2/5D = 4/5(195)

2/5D = 156

D = 390

If William has 195 marbles, let's find 4/5 of that.

195 * 4/5 = 156

156 is 2/5 of the marbles Daniel has.

Now we must multiply by the reciprocal

156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles

Daniel has 390 marbles.
