To find the additive inverse, we just change the sign of the number. In this case, the additive inverse of -234.76 is 234.76.
Therefore, calculating -123.45 - (-234.76) becomes -123.45 + 234.76 which equals 111.31.
So, the correct answer is -111.31.

Use the additive inverse to find −24 4/5−6 7/10. (1 point)
To find the additive inverse, we just change the sign of the number. In this case, the additive inverse of -6 7/10 is 6 7/10.
Therefore, calculating -24 4/5 - (-6 7/10) becomes -24 4/5 + 6 7/10.
To add these mixed numbers, we must first find a common denominator. The common denominator of 5 and 10 is 10.
Converting -24 4/5 to an improper fraction, we get -24 * 5/5 + 4/5 = -124/5
Converting 6 7/10 to an improper fraction, we get 6 * 10/10 + 7/10 = 67/10
Now, we can rewrite the expression -24 4/5 + 6 7/10 as -124/5 + 67/10
To add these fractions, we need to find a common denominator, which is 10.
-124/5 + 67/10 = -(124 * 2) / (5 * 2) + 67/10
= -248/10 + 67/10
= -181/10
Therefore, -24 4/5 - (-6 7/10) = -181/10.
So, the correct answer is -181/10.
Therefore, calculating -24 4/5 - (-6 7/10) becomes -24 4/5 + 6 7/10.

Converting -24 4/5 to an improper fraction, we get -24 * 5/5 + 4/5 = -124/5
Converting 6 7/10 to an improper fraction, we get 6 * 10/10 + 7/10 = 67/10
Now, we can rewrite the expression -24 4/5 + 6 7/10 as -124/5 + 67/10
To add these fractions, we need to find a common denominator, which is 10.
-124/5 + 67/10 = -(124 * 2) / (5 * 2) + 67/10
= -248/10 + 67/10
= -181/10
Therefore, -24 4/5 - (-6 7/10) = -181/10.
So, the correct answer is -181/10.
simplify
To simplify the expression -181/10, you can check if the fraction is already in its simplest form. In this case, the fraction -181/10 cannot be simplified any further because the numerator (-181) and denominator (10) do not share any common factors other than 1.
So, the simplified form of -181/10 is -181/10.
So, the simplified form of -181/10 is -181/10.
so do you mean the answer is -18 1/10?
Apologies for the confusion. You are correct. The simplified form of -181/10 is -18 1/10.
To simplify the fraction -181/10, divide the numerator (-181) by the denominator (10) to get the whole number part and the remainder:
-181 ÷ 10 = -18 with a remainder of 1
Therefore, the simplified form is -18 1/10.
To simplify the fraction -181/10, divide the numerator (-181) by the denominator (10) to get the whole number part and the remainder:

Consider 16–20.5. What is the solution? Represent the subtraction on a horizontal number line diagram.
To represent the subtraction 16 - 20.5 on a number line, you can start by marking the point corresponding to 16. Then, move to the left 20.5 units. Since the value being subtracted is greater than the starting point, this means we will move to the left of zero.
Here is a representation of 16 - 20.5 on a horizontal number line:
-|----|----|----|----|----|----|----|----|----|----|----|----|----|----|----|----|----|---
-40 -39 -38 -37 -36 -35 -34 -33 -32 -31 -30 -29 -28 -27 -26 -25 -24 -23

16
In this case, moving 20.5 units to the left from 16 will take us to the point -4.5. Therefore, 16 - 20.5 is equal to -4.5.
