Answer 1

Answer:
`2(2)/(3)`

Explanation:

`-2(1)/(3)-(-5)=`

Convert the mixed number to improper fraction. You can do this by multiplying the whole number times the denominator and adding the numerator; over the same denominator.

`-(2*3+1)/(3) -(-5)=`

Solve;

`-(6+1)/(3) -(-5)=`

`-(7)/(3) -(-5)=`

Now, get rid of the two negatives by multiplying.

`-(7)/(3) +5=`

Remember 5 has a 1 below; therefore, we can subtract these two fractions by getting both to a same denominator. Let's rewrite 5 as a fraction.

`-(7)/(3)+(5)/(1) =`

To be able to convert 1 to 3, we have to multiply by 3. Remember that if you change the denominator, you have to change the numerator as well.

`-(7)/(3)+(5)/(1) ((3)/(3) ) =`

Solve;

`-(7)/(3)+(15)/(3) =`

Subtract numerators and keep the same denominator.

`(-7+15)/(3)=(8)/(3)`

Convert to a mixed number. To do this, first, divide:

8/3=2

6

2

The 2 after the equal sign is the whole number, the two in the remainder is the numerator and the 3 is the denominator. Leaving our result as:
`2(2)/(3)`
