use the additive inverse to find -24 4/5 - 6 7/10
To find the additive inverse of a number, we simply change the sign of the number.
-24 4/5 can be written as -24 + 4/5. Changing the sign, the additive inverse of -24 4/5 is 24 - 4/5.
Similarly, -6 7/10 can be written as -6 + 7/10. Changing the sign, the additive inverse of -6 7/10 is 6 - 7/10.
Therefore, the additive inverse of -24 4/5 - 6 7/10 is 24 - 4/5 + 6 - 7/10.
thats not right
Apologies for the mistake.
To find the additive inverse of -24 4/5, we change the sign of the number:
-(-24 4/5) = 24 4/5
Similarly, to find the additive inverse of -6 7/10:
-(-6 7/10) = 6 7/10
So, the sum of -24 4/5 and -6 7/10 is:
24 4/5 + 6 7/10 = 30 11/10 or 30 1/10
do you mean 31 1/10
Apologies for the error in my previous response.
You are correct. The sum of -24 4/5 and -6 7/10 is:
24 4/5 + 6 7/10 = 31 1/10
is it negative
No, the sum of -24 4/5 and -6 7/10 is not negative. It is positive 31 1/10. The negative sign was removed when we found the additive inverse of each number.
all i have is -18 1/10 -31 1/2 -31 1/10 31 1/2
Let's solve for -18 1/10 - 31 1/2 - 31 1/10 + 31 1/2 using the additive inverse.
First, let's change all the signs of the given numbers to their additive inverse:
-(-18 1/10) = 18 1/10
-(-31 1/2) = 31 1/2
-(-31 1/10) = 31 1/10
-31 1/2 remains the same
Now, let's add all the numbers together:
18 1/10 + 31 1/2 + 31 1/10 + 31 1/2
To add fractions with different denominators, we need to find a common denominator:
The common denominator in this case is 10.
18 1/10 + 31 1/2 + 31 1/10 + 31 1/2 = (18*10 + 1)/10 + (31*5 + 1*5)/10 + (31*10 + 1)/10 + (31*5 + 1*5)/10
= (180 + 1)/10 + (155 + 5)/10 + (310 + 1)/10 + (155 + 5)/10
= 181/10 + 160/10 + 311/10 + 160/10
= (181 + 160 + 311 + 160)/10
= 812/10
Simplifying the fraction, we get:
812/10 = 406/5
Therefore, -18 1/10 - 31 1/2 - 31 1/10 + 31 1/2 is equal to -406/5.
