Pip was thinking of a number. Pip halves the number and gets an answer of 87.2. Form an
equation with x from the information.

x/2=87.2

Step-by-step explanation:

Pip was thinking of a number - Let's call this number x

Pip halve the number - So half of x = x/2  (or 1/2 x)

And gets an answer of 87.2  - x/2=87.2

So your equation would be x/2=87.2

I hope this helps :)
