Use the additive inverse to find 8.76−26.54
.
To find the difference between 8.76 and 26.54 using the additive inverse, we need to change the sign of one of the numbers and then add them together.
We can change the sign of 26.54 by multiplying it by -1:
-1 * 26.54 = -26.54
Now we can add 8.76 and -26.54:
8.76 + (-26.54) = -17.78
Therefore, 8.76 - 26.54 = -17.78.
Use the additive inverse to find −1223−(−856)
. Write the answer as a mixed number.
To find the difference between -1223 and -856 using the additive inverse, we need to change the sign of the second number and then add them together.
We can change the sign of -856 by multiplying it by -1:
-1 * -856 = 856
Now we can add -1223 and 856:
-1223 + 856 = -367
Therefore, -1223 - (-856) = -367.
To write this as a mixed number, we need to express it as a whole number and a proper fraction.
Since -367 is negative, we will write it as - (3 * 100 + 67).
So, -367 can be written as -3 and 67/100.
Therefore, -1223 - (-856) = -3 67/100.
To find the value of 8.76 - 26.54 using the additive inverse, we need to change the subtraction problem into an addition problem.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
To find the additive inverse of 26.54, we change the sign from positive to negative and keep the magnitude the same. So, the additive inverse of 26.54 is -26.54.
Now, we can rewrite the subtraction problem as an addition problem: 8.76 + (-26.54).
To add the numbers, we line up the decimal points and then add the digits, just like adding whole numbers:
8.76
+(-26.54)
___________
-17.78
Therefore, 8.76 - 26.54 = -17.78.
