Question

I'm stuck and don't know how to answer this problem. Huey has twice as many toys as Dewey and thrice as many toys as Louie, Huey has 12 more toys than Loue. How many fewer toys does Dewey have than Huey?

Answer 1

H = 2D = 3L

H = L+12

So

L+12 = 3L

12 = 2L

L=6

Louie has 6 Huey has 18, Dewey has 9

Dewey has 9 fewer toys than Heuey
