A recipe for glue for paper mache masks is shown. If you wanted to make 1/2 of the recipe, how much water would you need?
Recipe for glue : 2 1/4c water
2 1/4 = 9/4
(9/4) * (1/2) = 9/8 = 1 1/8
To make 1/2 of the recipe for glue, you need to determine half of 2 1/4 cups of water.
First, convert the mixed number 2 1/4 to an improper fraction:
2 1/4 = (2 * 4 + 1)/4 = 9/4
Next, divide the numerator (9) by 2 to find half of the amount:
9/4 ÷ 2 = 9/4 * 1/2 = 9/8
Therefore, to make 1/2 of the recipe, you would need 9/8 cups of water.
