Originally he needs 3/4 cups
If he is tripling it, he need 3 times 3/4.
You can see above since every number has a 1 under them you can write 3 as 3/1 if it make it easier dor you to understand.
Then, you multiply numerators and denominators with each other. 3 times 3 will give you 9 and 1 times 4 will give you 4.
So you got 9/4 whixh can also write as 2(times)1/4
