Answer 1

`(-117)/(10)`

Explanation:

1) Change the mixed fractions into improper fractions:

`-3(1)/(5) + (-8(1)/(2) )\\= (-16)/(5) - (17)/(2)`

2) Multiply the first fraction by 2/2 and the second fraction by 5/5 in order to create common factors on the denominator (You can do this because you are essentially multiplying by one, for example 2/2 = 1):

`(-16)/(5) *(2)/(2)  - (-17)/(2) * (5)/(5) \\ =(-32)/(10) - (85)/(10)`

3) Simplify the numerator(top part) while keeping the denominator(bottom part) the same:

`(-32)/(10) -(85)/(10)  \\\\=(-32 - 85)/(10)\\ \\= (-117)/(10)`
