What Is 3/4 Cup + 3/4 Cup?

It might help you to keep the following rule in mind: _ of a cup and _ of a cup is equal to 1 _ cups of whatever it is you are trying to measure. This is because two fractions of a single cup can only ever equate to less than two cups.

How Do I Add Together Fractions?
To work out exactly how many cups you will need in order to double your recipe, you will need to add the numerators from the two fractions together. In this case, it means adding 3 + 3, which equals 6, so now you have 6/4.

This is a vulgar fraction, since the fraction (numerator) side is greater than the whole (denominator). Use the following steps to solve this problem:

1. Divide the numerator by the denominator - 6/4 = 1, with remainder 2
2. This gives us one cup, and we place the remainder above the denominator - 2/4
3. We now have 1 and 2/4, but we can pare down 2/4 to 1/2, since it represents the same proportion
   

To answer your question then, you will need one and a half cups of whatever it is you are wishing to add to the recipe mix.

What Are Cup Measurements?
Cup measurements are most common in baking, where ingredients can easily be measured in cups and containers.

This method of measurement remains common and whilst not as exact as using defined parameters such as ounces, pounds and grams, it is still deployed in some recipes. This old concept is frequently used in many smaller kitchens where specific weight-based apparatus is not available.

1 and a half cups.

3/4 + 3/4 = 6/4, which when broken down will be: 4/4 = 1 whole + the 2/4 left over, which will break down to 1/2. So it will actually be 1 and 1/2 cups. 

Figure it out this way: 3/4 is 1/4 less than a cup and 1/4 more than a half cup, so if you know that 1/2 cup and 1/2 cup equals a whole cup.

You still have those two fourths from each cup left over, that you need to add those together too: 1/4 + 1/4 = 2/4. If you break 2/4 down by dividing in half, this equals a half cup. I hope I didn't confuse you more. I'm not a teacher.

That would be 6/4 of a cup, which is also equal to 1 and 1/2 cups.

One and one-half cups. Think of it in terms of a dollar: 3 quarters is 75 cents. Six quarters is a dollar and fifty cents. There you go!

(3/4) + (3/4) = 6/4
6/4 / 2 = 3/2
3/2 converted to decimal equals 1.5 (i.e. One and a half cups)

1 1/2 cups

1 1/2 cups
