Evaluate 4 1/2−2−5 2/3
To evaluate this expression, we need to follow the order of operations (PEMDAS).
First, we should simplify any mixed numbers or fractions.
4 1/2 can be written as 9/2, and 5 2/3 can be written as 17/3.
So, the expression becomes:
9/2 - 2 - 17/3
Next, we need to find a common denominator to combine the fractions. The common denominator of 2 and 3 is 6.
So, the expression becomes:
(9/2 * 3/3) - (2 * 3/3) - (17/3)
Simplifying further:
27/6 - 6/6 - 17/3
Now, we can combine the fractions:
(27 - 6 - 34)/6
Finally, we can simplify the expression:
-13/6
Therefore, the value of 4 1/2 - 2 - 5 2/3 is -13/6.
Evaluate this expression.
42.86 − 23.42
To evaluate the expression 42.86 - 23.42, you can subtract the two numbers:

Consider this expression:
1/4 − 0.5 + 1/2 − 0.25 + 3/5 + 0.4
You are asked to find the sum by using fractions. Which expression could you use?
To find the sum of the given expression using fractions, we can write all the numbers as fractions with a common denominator and then add them together.
The given expression is:
1/4 − 0.5 + 1/2 − 0.25 + 3/5 + 0.4
To find a common denominator for these fractions, we need to find the least common multiple (LCM) of 4, 2, and 5. The LCM of these numbers is 20.
Now, let's rewrite the expression with fractions having a denominator of 20:
(1/4)(5/5) - (0.5)(20/20) + (1/2)(10/10) - (0.25)(20/20) + (3/5)(4/4) + (0.4)(20/20)
Simplifying each term:
5/20 - 10/20 + 10/20 - 5/20 + 12/20 + 8/20
Combining the terms:
(5 - 10 + 10 - 5 + 12 + 8)/20
Simplifying the numerator:
(10 + 10 + 8)/20
Combining and simplifying the numerator:
28/20
Now, we can simplify the fraction:
28/20 = 7/5
Therefore, the sum of the given expression using fractions is 7/5.
Evaluate this expression.

To find a common denominator, we need to find the least common multiple (LCM) of 2 and 4, which is 4.
Now, let's rewrite the fractions with a denominator of 4:
(1/2)(2/2) + (3/4)(1/1)
Simplifying each term:
2/4 + 3/4
Combining the fractions:
(2 + 3)/4

Therefore, the value of the expression is -9.99.
The temperature in Antarctica at noon is 14°F. By 9:00PM, the temperature had dropped by 16.2 degrees. What was the temperature at 9:00PM?
To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the initial temperature of 14°F.
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM was -2.2°F.
Simplify.
7 2/3 + −5 1/4
To simplify the expression 7 2/3 + −5 1/4, we first need to convert the mixed numbers to improper fractions.
7 2/3 is equivalent to (3 * 7 + 2) / 3 = 23/3.
-5 1/4 is equivalent to (4 * -5 + 1) / 4 = -21/4.
Now we can add the fractions:

-5 1/4 = (4 * -5 + 1)/4 = -19/4
Now, re-writing the expression with fractions:
23/3 + -19/4
Next, we need to find a common denominator for 3 and 4, which is 12.
To convert 23/3 to have a denominator of 12, we multiply the numerator and denominator by 4:
(23/3) * (4/4) = 92/12
To convert -19/4 to have a denominator of 12, we multiply the numerator and denominator by 3:
(-19/4) * (3/3) = -57/12
Now, the expression becomes:
92/12 + -57/12
Adding the fractions:
(92 + -57)/12 = 35/12
