Answer:
-3 3/4
Explanation:
So we have:
-1 1/4 + (-2 1/2)
Before solving this, lets just clean it up.
First off, since we know that a + and - sign equals a - sign, we can rewrite it as:
-1 1/4 - (2 1/2)
We need to also get a common denominator, which would be 4. The first fraction already has a denominator of 4, so it doesnt change. However, the second fraction is 1/2, and we need to multiply both sides by 2 to change the denominator from 2 to 4:
-1 1/4 - (2 2/4)
Now lets solve:
I will do the fraction seperate from the whole number to make it simpler:
-1 - 2
A negative subtracted makes it a larger negative so:
-3
-1/4 - 2/4
Again, a negative subtracted makes it a larger negative:
-3/4
Now recombine the numbers:
-3 3/4
So this is your answer.
Hope this helps!
