Answer 3

Multiply, it's not that difficult. They teach you that in grade 4.

Answer 4

Yeah so you see that x/8....you want to multiply that and the other parts of the question to isolate x

2/3<x/8<1

turns into

16/3 < x < 8
16/3 is equal to 5.33

so x is less than 8 but more than 5.33 so x could be 6 or 7
