Miranda is making lemonade from a powdered mix she needs to add 3 cups of powdered mix to a large picture of water but she only has a scoop that holds 2 ounce is how many 2 ounce cups would she use

 if it takes 1 and 3/4 cups to make 1 batch how many cups will it take to make 2 and 1/2 batches. 4.375 cups = x. You can also add the cups one batch and then a half batch at a time. 7/4 + 7/4 + (7/4*1/2) = x. multiply the first two (7/4) by 2/2. Then you have 14/8 + 14/8 + 7/8 = 35/8 = 4.375 cups.
