D) 134 - (-16) = 118
Therefore, the correct answers are B), C), and D).
You have answered the question incorrectly. Please view the following explanation below.
-39 - (-28) = -11 89 - (-17) = 106 152 - 200 = -48
-39 - (-28) ? -39 + 28 = -11
89 - (-17) ? 89 + 17 = 106
152 - 200 = -48 ? Find the difference and use the sign of the number with the greater absolute value.

What is the value of the expression −6 4/9 − 1 1/3 ?
A 7 7/9
B -7 7/9
C 5 1/9
D -5 1/9
To simplify the expression -6 4/9 - 1 1/3, we first convert the mixed numbers to improper fractions.
-6 4/9 can be written as -59/9.
1 1/3 can be written as 4/3.
Next, we find a common denominator, which is 9.
-59/9 - 4/3 = -177/27 - 36/27 = -213/27.
Simplifying -213/27, we get the mixed number -7 7/9.
Therefore, the answer is B) -7 7/9.
What is 4−1 1/4 + 1/2
A 2 7/16
B 2 3/4
C 2 1/4
D 3 1/4
To simplify the expression 4 - 1 1/4 + 1/2, we first convert the mixed number to an improper fraction.
1 1/4 can be written as 5/4.
Next, we find a common denominator, which is 4.
4 - 5/4 + 1/2 = 16/4 - 5/4 + 2/4.
Simplifying the expression, we get 13/4.
To convert 13/4 back to a mixed number, we divide the numerator (13) by the denominator (4) and write the remainder as a fraction:
13 ÷ 4 = 3 with a remainder of 1.
Therefore, 13/4 can be written as 3 1/4.
Therefore, the answer is D) 3 1/4.

Find the sum - 3/2 + 8/5
A -1/2
B -3/10
C 1/10
D 5/2
To find the sum of -3/2 and 8/5, we need to find a common denominator.
The least common multiple of 2 and 5 is 10.
Converting the fractions to have a denominator of 10:
-3/2 becomes -15/10
8/5 becomes 16/10
Now, we can add the fractions:
-15/10 + 16/10 = 1/10
Therefore, the sum is C) 1/10.
