Grace is making 2 ½ batches of muffins for her school’s annual bake sale. If one batch of muffins requires 1 ¼ cups of flour, how many cups of flour does Grace need to make 2 ½ batches of muffins?
2-1/2/1-1/4 = (5/2)/(5/4) = 5/2 x 4/5 = 20/10 = 2 cups flour needed.
To find the total amount of flour needed, we need to multiply the amount of flour needed for one batch by the number of batches Grace is making.
First, let's convert 2 ½ batches to an improper fraction:
2 ½ = 2 + ½ = 2 + 1/2 = 4/2 + 1/2 = 5/2.
Now, multiply the amount of flour needed for one batch by the number of batches:
(1 ¼) x (5/2) = (5/4) x (5/2) = (25/8) cups of flour.
Therefore, Grace needs 25/8 cups of flour to make 2 ½ batches of muffins.
To find out how many cups of flour Grace needs to make 2 ½ batches of muffins, we first need to determine the amount of flour required for one batch of muffins.
One batch of muffins requires 1 ¼ cups of flour.
Now, to calculate the amount of flour required for 2 ½ batches of muffins, we need to multiply the amount of flour required for one batch by 2 ½.
Multiplying the amount of flour required for one batch (1 ¼ cups) by 2 ½ can be done as follows:
1 ¼ cups * 2 ½ = (5/4) cups * (5/2) = (5 * 5) / (4 * 2) = 25/8 cups
Therefore, Grace needs 25/8 cups of flour to make 2 ½ batches of muffins.
