-1 1/3 + (-4 2/3)=
To solve this equation, we need to convert the mixed numbers to improper fractions.
-1 1/3 is equivalent to -(3/3 + 1/3) = -(4/3)
Similarly, -4 2/3 is equivalent to -(3/3 + 2/3) = -(5/3)
Now we can add the fractions:
-(4/3) + -(5/3) = -9/3
Simplifying the fraction gives us: -3
Therefore, -1 1/3 + (-4 2/3) = -3.
−31/6+53/4=
To add the fractions, we need to find a common denominator.
The least common multiple of 6 and 4 is 12.
Now we can rewrite the fractions with the common denominator of 12:
-31/6 = -31/6 * 2/2 = -62/12
53/4 = 53/4 * 3/3 = 159/12
Now we can add the fractions:
-62/12 + 159/12 = (159 - 62)/12 = 97/12
Therefore, -31/6 + 53/4 = 97/12.
However, we can also simplify the fraction:
97/12 = (8 * 12 + 1)/12 = 8 + 1/12
So, -31/6 + 53/4 can be simplified to 8 1/12.
