Step-by-step explanation:

Given numbers,

-2/3 and 1/5

First of all we will add both the

numbers as asked to do in question,

= -2/3+1/5

We'll have to find their LCM firstly,

= {(-2×5)+(1×3)}/3

= (-10+3)/3= -7/3

And now it's asked to find product of both

number,

= -2/3×1/5

= -2/15

Now, it's asked to divide the sum and product

of both the numbers,

= -7/3 ÷ -2/15

= -7/3 × 15/-2

= -105/-6

= 35/2 (Minus signs in both numerator and denominator

will get cancelled)

17.5(Seventeen whole one upon two)
