Question

Evaluate x+y when x=−4\5 and y=1\3. Write your answer as a fraction or mixed number in simplest form.

Answer 1

When x=−4\5 and y=1\3 we get x+y = -7/15

Explanation:

We are given :

x=−4\5 and y=1\3

We need to evaluate : x+y

Solving:

`x+y\\=-(4)/(5)+(1)/(3)`

Taking LCM of denominators 5 and 3, we get 15

`=(-4*3+1*5)/(15)\\=(-12+5)/(15)\\=(-7)/(15)`

So, when x=−4\5 and y=1\3 we get x+y = -7/15
