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.
