use the additive inverse to find -24 4/5-6 7/10
To find the sum using the additive inverse, we change the sign of the second number and then proceed with addition.
The additive inverse of -234.76 is 234.76.
Now we can rewrite the equation as:
-123.45 + 234.76
Next, we can add these two numbers together:
-123.45 + 234.76 = 111.31
Therefore, the sum is 111.31.
To find the distance between two numbers on a number line, we subtract the smaller number from the larger number. In this case, 6.5 is the larger number and -7.2 is the smaller number.
Therefore, the distance between 6.5 and -7.2 can be calculated as:
6.5 - (-7.2)
When we subtract a negative number, it is equivalent to adding the positive number.
6.5 - (-7.2) is the same as 6.5 + 7.2.
Now we can add these two numbers together:
6.5 + 7.2 = 13.7
Therefore, the distance between 6.5 and -7.2 on the number line is 13.7.
To subtract -6 from -8, we first change the subtraction sign into addition by applying the additive inverse.
-6 - (-8) = -6 + 8
Now, we can simply add the two numbers together:
-6 + 8 = 2
Therefore, the result is 2.
To subtract 17 from -18, we can rewrite the expression as an addition problem using the additive inverse.
17 - (-18) = 17 + 18
Now, we can add the two numbers together:
17 + 18 = 35
Therefore, the result is 35.
To use the additive inverse, we simply change the sign of the number.
The additive inverse of -24 4/5 is 24 4/5.
The additive inverse of -6 7/10 is 6 7/10.
Therefore, when we subtract -6 7/10 from -24 4/5, we can rewrite the problem as:
-24 4/5 + 6 7/10
Now, we can add these two numbers together:
-24 4/5 + 6 7/10 = -17 8/5 + 6 7/10
First, we need to convert the fractions to a common denominator. The common denominator of 5 and 10 is 10.
Converting -17 8/5 to a fraction with a denominator of 10:
-17 8/5 = -17 (8/5 * 2/2) = -17 (16/10) = -17 16/10
Now, the problem becomes:
-17 16/10 + 6 7/10
Next, we can combine the whole numbers and fractions separately:
-17 + 6 = -11
16/10 + 7/10 = 23/10
Therefore, the sum is:
-11 23/10 or -11 2/10 + 23/10 = -11 1/5.
