Raymond bought 3/4 of a dozen rolls. how many rolls did he buy?

First you need to know that a dozen is 12.

Next, you need to make that into a fraction by putting it over 1: 12/1

Then, you multiply that by your first fraction: 3/4 x 12/1 = 36/4

Finally, simplify 36/4 = 9

Raymond bought 9 rolls.

3/4x12=36/4 if you simplify you would get 9
