#### Explanation:

First, we convert the mixed fraction into an improper fraction by multiplying the whole number by the denominator, adding the product to the numerator and placing the result on the same denominator.

Hence:

Keeping the minus sign outside, place the two terms inside brackets. The plus sign will change to a minus sign because of this.

Since the denominator is the same, we simply subtract the numerators.

Since the numerator is completely divisible by the denominator, we reduce the fraction.

Open the brackets keeping the minus sign.
