Answer:
18 muffins
Step-by-step explanation:
Amount of flour Maggie used
Total amount of flour she bought - Amount of flour left over.
= 45oz - 14.72 oz
= 30.28 oz of flour
She used 17.5 oz to make a loaf of bread, and 0.71 oz for each muffin.
Hence,
Let the number of muffins = x
17.5 + 0.71x = 30.28
0.71x = 30.28 - 17.5
0.71x = 12.78
x = 12.78/0.71
x = 18 muffins
Therefore, Maggie made 18 muffins

Answer:
A: 66/21
E: 22/7
Step-by-step explanation:
The offered choices reduce to 3 1/7 or to 3. The best approximations of those given are the ones that reduce to 3 1/7.
A: 66/21 = 22/7 = 3 1/7
B: 60/20 = 3
C: 21/7 = 3
D: 45/15 = 3
E: 22/7 = 3 1/7
___
<em>Comment on pi approximations</em>
The ratio 22/7 differs from π by about 0.04%. A better approximation is 355/113, which differs from π by about 0.000008%. The approximation 3.14 differs from π by about 0.05%.
