My Maths Strategy ( DLO )

So Dairy one sells 36 ice blocks and 3/4 of these ice blocks are raspberry. Dairy Two sells 28 ice blocks and 3/7 of these are raspberry. Which dairy sells the most raspberry ice blocks??

Dairy One: Well first of all I know that 9 times 4 equals 36 and 9 times 3 equals 27 so there is 27 raspberry ice blocks for dairy one.

Dairy Two: First of all I know that 28 divide 7 equals 4 and 4 times 3 equals 12 so there is 12 raspberry ice blocks in dairy two.

So Dairy One wins because Dairy one has 27 raspberry ice blocks and Dairy Two only has 12.
