Arecipe calls for 1 3/4 cups of flour. if the recipe is tripled, how much flour is needed?

21/4 or 5 1/4 because you do 3 times 7/4 and that = 21/4

Ok, since the recipe is being tripled, it means you need to multiply by 3

So you have to do 1 3/4 x 3/1

First, you need to change 1 3/4 into an improper fraction and that is 7/4

Now, your equation is 7/4 x 3/1

And that equals 21/4

To simplify, you need to do 21 divided by 4

21 divided by 4 is 5 r1
and that will be 4 1/4

So the recipe will call for 4 1/4 cups of flour

x/7.50 = 15

x= 7.50 / 15 divide

x = 2
