Answer:
See Below
Explanation:
3 out of 5 of the 60 total blocks are red, that means every 3 of 5 random we take would be RED.
That is 3/5ths of 60 are red. We multiply and figure out.

So we can say there are 36 red blocks from the total 60 Blocks.
Briana needs to make a design that uses 32 RED BLOCKS. Are there enough??
Yes of course, because 36 > 32
So, it is reasonable for Briana to think there are enough blocks to make her design.
