Mario was making cookies. He mixed 2 1⁄2 cups of flour, 11⁄4 cups of sugar and 1⁄2 cup of brown sugar together in a bowl. How many cups did he have altogether?
To find the total number of cups Mario had after mixing the ingredients, we need to add up the amounts of flour, sugar, and brown sugar.
First, let's add the cups of flour and sugar.
Mario had 2 1/2 cups of flour and 1 1/4 cups of sugar.
To add these measurements, we need to find a common denominator, which in this case is 4.
2 1/2 cups can be written as 2 2/4 cups.
Now, we can add the amounts:
2 2/4 cups + 1 1/4 cups = 3 3/4 cups.
Next, let's include the 1/2 cup of brown sugar.
Adding 3 3/4 cups and 1/2 cup:
3 3/4 cups + 1/2 cup = 7/4 cups + 1/2 cup.
To find the sum, we need to have a common denominator. The common denominator for 4 and 2 is 4.
Rewriting 1/2 cup as 2/4 cups:
7/4 cups + 2/4 cups = 9/4 cups.
Therefore, Mario had a total of 9/4 cups of flour, sugar, and brown sugar altogether.
To express this as a mixed number, we divide the numerator (9) by the denominator (4):
9 ÷ 4 = 2 remainder 1.
Thus, the mixed number representation is 2 1/4 cups.
Therefore, Mario had a total of 2 1/4 cups of ingredients altogether.
