Here, we want to select which of the fractions are rational

To get this, we need to understand what rational numbers are

Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero

From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero

This means **all the given fractions are rational**

If im correct it would be -2(2)+4(-2)-5 which is -4-8-5 which would be -17

**Answer:**

Y=**2****1**

X=**8**

**Step-by-step explanation:**

In the middle there is a right angle

therefore **2****7**** ****+****3****y****=****9****0**

Y will be** ****2****1**

Then x+27+63+8x+18=180

x=**8**

**Hence**** ****8****+****2****7****+****3****(****2****1****)****+****8****(****8****)****+****1****8****=****1****8****0**
