A recipe for 1 batch of muffin included 2/3 cup of raisins. Ina made 2 1/2 batches of muffins. How many cups of raisin did she use. Is the answer 1 5/6
I also Wanted to answer the question but I don't know the answer. Can you help me out ?
1 2/3 :)
No.
5/2 * 2/3 = 10/6 = 1 4/6 = 1 2/3
To find out how many cups of raisins Ina used, we need to calculate the total amount of raisins for 2 1/2 batches of muffins.
First, let's calculate the amount of raisins for 1 batch of muffins. Given that 1 batch requires 2/3 cup of raisins:
Number of cups of raisins in 1 batch = 2/3 cup.
Now, we can determine the amount of raisins for 2 1/2 batches of muffins. We'll multiply the amount of raisins for 1 batch by 2 1/2:
Number of cups of raisins in 2 1/2 batches = (2/3) * 2 1/2.
To multiply a whole number by a fraction, we convert the whole number into an improper fraction:
2 1/2 = (2 * 2 + 1) / 2 = 5/2.
Now, we can complete the calculation:
Number of cups of raisins in 2 1/2 batches = (2/3) * (5/2).
To multiply fractions, we multiply the numerators together and the denominators together:
Number of cups of raisins in 2 1/2 batches = (2 * 5) / (3 * 2).
Simplifying the fraction:
Number of cups of raisins in 2 1/2 batches = 10/6.
Since 10/6 can be simplified further, let's divide both numerator and denominator by their greatest common divisor, which is 2:
Number of cups of raisins in 2 1/2 batches = (10/2) / (6/2) = 5/3.
Therefore, Ina used 5/3 cups of raisins for 2 1/2 batches of muffins. However, if we convert this to a mixed number, the answer is indeed 1 2/3 (not 1 5/6 as you mentioned).
