Question

Triston is baking specialty bread for the school bake sale. She has 10 1/2 cups of flour. The recipe for 1 loaf of bread calls for 2 1/3 cups of flour. How many whole loaves of bread can she make?

a) 3 loaves
b) 4 loaves
c) 5 loaves
d) 6 loaves

Answer 1

Triston can make 4 loaves of bread.

Step-by-step explanation:

To find out how many whole loaves of bread Triston can make, we need to divide the total amount of flour she has by the amount of flour needed for one loaf of bread. Triston has 10 1/2 cups of flour, and each loaf requires 2 1/3 cups of flour.

We can convert the mixed number 10 1/2 to an improper fraction by multiplying the whole number (10) by the denominator (2) and adding the numerator (1). This gives us 21/2 cups of flour.

Now we can divide 21/2 by 2 1/3. To divide fractions, we need to find the reciprocal of the second fraction and then multiply. The reciprocal of 2 1/3 is 3/7. So, we have (21/2) * (3/7).

Multiplying the numerators (21 * 3) gives us 63, and multiplying the denominators (2 * 7) gives us 14.

Therefore, Triston can make 63/14 loaves of bread using the amount of flour she has. This is equivalent to 4 and 5/14 loaves of bread. Since we're looking for whole loaves, we can round down to 4 loaves of bread.
