How do you simplify #-1 2/3 + (-2 1/4) #?
Take a look at the explanation.
To make things easier, I would start off by turning those mixed fractions into improper ones.
I would then add them, like I would add any other normal fraction.
First, find the Least Common Denominator (LCD) between the two fractions. I found that by multiplying
We multiply the numerators and the denominators and this is what we get:
Add the numerators (but do not add the denominators) and now we have:
Let's turn this into a mixed fraction (just for the sake of it):
And there goes your answer!
