Question

a recipe calls for 1 and 3/4 cups of flour. How many cups will you need if you are preparing 3 batches of the recipe?

Answer 1

You will need 5 and 1/4 cups. Since one batch is 1 and 3/4 cups, to make 3 batches, you multiply 1 3/4 times 3.

1 3/4 x 3 = 5 1/4

Answer 2

The first thing we need to distinguish is what 1 and 3/4 means. So, 3/4 = .75, so 1 and 3/4 = 1.75

So, we need 1.75 cups of flour for one batch, since you're making three batches, you need three times as much, so

1.75 * 3

5.25 is the answer, to put it back in to fractions,

5 and 1/4 cups of flour are needed.
