each tile in the model represents 1/4. How many tiles make a group of 3/4? and there is 24 tiles

? tiles

A group of 3/4 would be represented by 3 tiles, since each tile represents 1/4. Therefore, to have a group of 3/4, you would need 3 tiles.

To find out how many tiles make a group of 3/4 in a total of 24 tiles, you would divide 24 by 3:

24 tiles / 3 tiles = 8 groups of 3/4

Therefore, in a total of 24 tiles, there would be 8 groups of 3/4.
