Given:
grapes = 2 1/2 pounds
apples = 1 1/4 times as many pounds as grapes.
For easier computation, let us convert these fractions into numbers with decimal places.
2 1/2 pounds = 2.50 pounds
1 1/4 times = 1.25
Apples = 2.50 pounds * 1.25 = 3.125 pounds of apples.
Or we still use fractions. We need to convert the mixed fractions into improper fractions.
2 1/2 = 5/2
1 1/4 = 5/4
5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds
(72÷2)³ - 7 · 9 ÷ 9
First, parenthesis
72÷2 is 36
Next, exponents.
36³ is 46656.
Then, multiplication.
7 · 9= 63
After that, division.
63 ÷ 9 is 7
Finally, subtraction.
46656 - 7 is 46649
the diamiter is the two out side numbers minused by 3.14
first one is 40 and then 65 and then 65 again
