Stella bought a 100-pound sack of flour to make bread for the bakery. If 7/8 of a pound of flour is needed for each loaf, how many loaves can she make? What fraction of a pound of flour is left over?
(1 loaf / (7/8) pound )(100 pounds) = 800 /7 loaves
= 114 2/7 loaves
so 114 loaves + 2/7 of a loaf
how many pounds is 2/7 of a loaf?
(2/7) loaf * ( 7/8) pounds/loaf = 2/8 = 1/4 pound left over
100 / (7/8)
100 * (8/7) = 800/7 = 114 loaves
114*(7/8) = 99 3/4 pounds
114 loaves plus 0.285714285714 (left over)
Divide 7/8 = .875
.875 into 100 pounds of flour = 114 loaves with 2/7 or .02857+ left over.
To find out how many loaves Stella can make, we need to divide the total weight of the flour by the amount of flour needed per loaf.
First, let's convert the fraction 7/8 into decimal form. To do this, we divide the numerator (7) by the denominator (8):
7 ÷ 8 = 0.875
So, Stella needs 0.875 pounds of flour for each loaf.
Now, let's divide the total weight of the flour (100 pounds) by the amount needed per loaf (0.875 pounds):
100 ÷ 0.875 = 114.2857...
Since we can't have a fraction of a loaf, we round down to the nearest whole number. Therefore, Stella can make 114 loaves of bread.
To find out what fraction of a pound of flour is left over, we need to deduct the amount of flour used from the total weight of the flour.
The amount of flour used is 114 loaves multiplied by 0.875 pounds per loaf:
114 × 0.875 = 99.75 pounds
To find the leftover amount, we subtract the amount used (99.75 pounds) from the total weight (100 pounds):
100 - 99.75 = 0.25 pounds
Therefore, Stella has 0.25 pounds of flour left over.
The fraction of a pound of flour left over is 1/4, which is the same as 0.25 when written as a decimal.
