A recipe call for 3/4 cups of flour for a batch of cookies. Phillip makes 2 1/2 batchers. How much flour will he use
3/4 * 5/2 = 15/8 = 1 7/8
Or you could convert to decimals.
0.75 * 2.5 = 1.875
To find out how much flour Phillip will use, you need to multiply the amount of flour required for one batch by the number of batches he makes.
First, let's convert the mixed number to an improper fraction.
2 1/2 can be rewritten as 2 + 1/2. To turn the whole number 2 into a fraction, we multiply it by the denominator of the fraction (2 x 2 = 4). Now, we add the numerator of the fraction to the result (4 + 1 = 5). So, 2 1/2 is equivalent to 5/2.
Now, we can calculate how much flour Phillip will use by multiplying the amount required for one batch (3/4 cups) by the number of batches (5/2):
(3/4) x (5/2) = (3 x 5) / (4 x 2) = 15/8,
So, Phillip will use 15/8 cups of flour for 2 1/2 batches of cookies.
