Question

Dan has some marbles. Ellie has twice as many marbles as dan.frank has 15 marbles. Dan,Ellie and frank have a total of 63 marbles. How many does dan have

Answer 1

Answer:

Dan has 16 marbles.

Step-by-step explanation:

We know that Frank has 15 marbles and that the three people combined have 63 marbles, therefore the first step is to substrack the 15 marbles of Frank out of the total.

63-15=48

Now, Dan and Ellie have 48 marbles between each other but we know that Ellie has twice the amount that Dan has. So we first need to divide 48 by three

48/3=16

If there would be three people instead of two (Dan and Ellie) then each of them would have 16 marbles. but in this case, Ellie has twice the amount, therefore Ellie has 32 (16x2) and Dan has the remaining 16 marbles

Dan= 16 marbles

Ellie=32 marbles

Frank=15 marbles

Total amount= 16+32+15=63.

Answer 2

16 is how many dan has.
