Use the additive inverse to find - 123.45 - (-234.76).
I apologize for the confusion and the incorrect responses. If you have access to a calculator, that would be a great option to accurately find the solution to −12 2/3 - (−8 5/6). This way, you can get the correct answer without any further confusion.
nope. the correct answer is 23 1/2
Since the additive inverse of a number is the number with the opposite sign, we can rewrite the expression as follows:
-123.45 - (-234.76)
Using the additive inverse of -234.76, we change the subtraction to addition and change the sign of -234.76:
-123.45 + 234.76
Now we can simply add the numbers together:
-123.45 + 234.76 = 111.31
Therefore, -123.45 - (-234.76) = 111.31.
Use the additive inverse to find -24 4/5 - 6 7/10
To find the sum of two mixed numbers using the additive inverse, we can rewrite the expression as follows:
-24 4/5 - 6 7/10
First, we need to convert both mixed numbers to improper fractions.
-24 4/5 can be rewritten as -24 + 4/5, and -6 7/10 can be rewritten as -6 + 7/10.
Next, we find the common denominator for 5 and 10, which is 10.
-24 4/5 becomes -24 + (4/5) * (10/10) = -24 + 8/10.
Similarly, -6 7/10 becomes -6 + (7/10) * (5/5) = -6 + 35/50.
Now we can rewrite the expression as:
-24 + 8/10 - 6 + 35/50.
To add the fractions, we need to find a common denominator, which is 10.
-24 + 8/10 - 6 + 35/50 = -24 + 8/10 - 6 + (35/50) * (2/2) = -24 + 8/10 - 6 + 70/100.
Now we can combine the terms:
-24 + 8/10 - 6 + 70/100 = -24 - 6 + 8/10 + 70/100 = -30 + 8/10 + 70/100.
To add the fractions, we need to find a common denominator, which is 100.
-30 + 8/10 + 70/100 = -30 + (8/10) * (10/10) + 70/100 = -30 + 80/100 + 70/100 = -30 + 150/100.
Now we can simplify the expression:
-30 + 150/100 = -30 + 150/100 = -30 + 1.5 = -28.5.
Therefore, -24 4/5 - 6 7/10 = -28.5.
Use the additive inverse to find 8.76−26.54.(1 point)
Since we need to use the additive inverse, we can rewrite the expression as follows:
8.76 + (-26.54)
By using the additive inverse, we change the subtraction to addition and change the sign of -26.54.
Now we can simply add the numbers together:
8.76 + (-26.54) = -17.78
Therefore, 8.76-26.54 = -17.78.
Use the additive inverse to find −12 2/3−(−8 5/6). Write the answer as a mixed number. (1 point)
To find the difference of two mixed numbers using the additive inverse, we can rewrite the expression as follows:
-12 2/3 - (-8 5/6)
First, we need to convert both mixed numbers to improper fractions.
-12 2/3 can be rewritten as -12 + 2/3, and -8 5/6 can be rewritten as -8 + 5/6.
Next, we find the common denominator for 3 and 6, which is 6.
-12 2/3 becomes -12 + (2/3) * (2/2) = -12 + 4/6.
Similarly, -8 5/6 becomes -8 + (5/6) * (1/1) = -8 + 5/6.
Now we can rewrite the expression as:
-12 + 4/6 - (-8) + 5/6.
To add the fractions, we need to find a common denominator, which is 6.
-12 + 4/6 - (-8) + 5/6 = -12 + 4/6 - (-8) + (5/6) * (1/1) = -12 + 4/6 + 8 + 5/6.
Now we can combine the terms:
-12 + 4/6 + 8 + 5/6 = -12 + 8 + 4/6 + 5/6 = -4 + 4/6 + 5/6.
To add the fractions, we need to find a common denominator, which is 6.
-4 + 4/6 + 5/6 = -4 + (4/6) * (1/1) + 5/6 = -4 + 4/6 + 5/6 = -4 + 9/6.
Now we can simplify the expression:
-4 + 9/6 = -4 + 1 and 3/6 = -4 + 1 and 1/2 = -3 and 1/2.
Therefore, -12 2/3 - (-8 5/6) = -3 1/2.
