To find the sum using fractions, we can convert the decimal numbers into fractions with a common denominator. The common denominator for 4, 2, 5, and 10 is 20. Therefore, we can rewrite the expression as:
5/20 - 10/20 + 10/20 - 5/20 + 12/20 + 8/20
Simplifying this expression, we get:
(5 - 10 + 10 - 5 + 12 + 8)/20
This further simplifies to:
20/20
And the sum is 1.
5/20 - 10/20 + 10/20 - 5/20 + 12/20 + 8/20
Simplifying this expression, we get:
(5 - 10 + 10 - 5 + 12 + 8)/20
This further simplifies to:
20/20
And the sum is 1.

Apologies for the confusion in my previous response. You are absolutely correct. Converting the decimals into fractions:
0.5 = (1/2)
0.25 = (1/4)
0.4 = (2/5)
To find the sum, we add/subtract the fractions from left to right:
(1/2) - (1/4) + (1/2) - (1/4) + (3/5) + (2/5)
Simplifying this expression, we get:
2/2 + 1/5 + 2/5
Which further simplifies to:
1 + 1/5 + 2/5
And the sum is indeed 1.
0.5 = (1/2)
0.25 = (1/4)
0.4 = (2/5)
To find the sum, we add/subtract the fractions from left to right:
(1/2) - (1/4) + (1/2) - (1/4) + (3/5) + (2/5)
Simplifying this expression, we get:
2/2 + 1/5 + 2/5
Which further simplifies to:
1 + 1/5 + 2/5
And the sum is indeed 1.

To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the noon temperature of 14°F.
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM was -2.2°F.
So, the correct answer is:
A) -2.2°F
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM was -2.2°F.
So, the correct answer is:
A) -2.2°F

To evaluate 412 − 2 − 523, we must perform the operations in the correct order. The subtraction of 2 from 412 yields:
410 − 523
To subtract 523 from 410, we must borrow from the tens place:
410 − 523
(400 − 500) − (20 − 3)
-100 - 17
-117
Therefore, the correct answer is:
D) –117
410 − 523

To evaluate 4 1/2 - 2 - 5 2/3, we need to convert all the mixed numbers into improper fractions first.
4 1/2 is equal to (4 * 2 + 1) / 2 = 9/2
5 2/3 is equal to (5 * 3 + 2) / 3 = 17/3
Now, we can rewrite the expression as:
9/2 - 2 - 17/3
To subtract 2 from 9/2, we need to convert 2 into the fraction with a denominator of 2.
2 = 4/2
Now we can rewrite the expression again:
9/2 - 4/2 - 17/3
To subtract 4/2 from 9/2, we get:
(9 - 4) / 2 = 5/2
Now we have:
5/2 - 17/3
To subtract 17/3 from 5/2, we need to find the common denominator, which is 6.
(5/2) * (3/3) = 15/6
(17/3) * (2/2) = 34/6
Now we can rewrite the expression again:
15/6 - 34/6
To subtract 34/6 from 15/6, we get:
(15 - 34) / 6 = -19/6
Therefore, the correct answer is:
D) -19/6
4 1/2 is equal to (4 * 2 + 1) / 2 = 9/2
5 2/3 is equal to (5 * 3 + 2) / 3 = 17/3
Now, we can rewrite the expression as:
9/2 - 2 - 17/3
To subtract 2 from 9/2, we need to convert 2 into the fraction with a denominator of 2.
2 = 4/2
Now we can rewrite the expression again:
9/2 - 4/2 - 17/3
To subtract 4/2 from 9/2, we get:
(9 - 4) / 2 = 5/2
Now we have:
5/2 - 17/3
To subtract 17/3 from 5/2, we need to find the common denominator, which is 6.
(5/2) * (3/3) = 15/6
(17/3) * (2/2) = 34/6
Now we can rewrite the expression again:
15/6 - 34/6
To subtract 34/6 from 15/6, we get:
(15 - 34) / 6 = -19/6
Therefore, the correct answer is:
D) -19/6
