Answer:
3
Explanation:
Hi,
To begin, we have one mixed number and one fraction. In order to solve, we have to turn the mixed number into an improper fraction.
2 3/4 as an improper fraction is 11/4. We know this because we multiply the denominator by the whole number which is 4 x 2 = 8 and then add the result to the numerator which is 8 + 3 = 11. The denominator stays the same.
So...
11/4 - (-1/4)
- (-) always turns into a +. So when subtracting a negative, take those two subtraction signs, cancel them out, and add instead.
11/4 + 1/4 = 12/4
We can add straight across since they have the same denominator.
12/4 = 3
I hope this helps :)
