Question

Nelson has been collecting he has collected 7 whole and 5 over 12 dozen marbles so far how many marbles are in his collection

Answer 1

Alright, lets get started.

1 dozen, means 12

Collecting 1 dozen marbles means 12 marbles.

Nelson has 7 whole dozens means = 7 * 12 = 84

And he has 5/12 dozen that means = 5 / 12 * 12 = 5

So, in total = 84 + 5 = 89

Means Nelson has 89 marbles in his collection. Answer

Hope it will help :)
