Let us suppose, we pour x glass of water.
The given jug is of 6 liters. And the glass of water was seven- eighths of a liter. Hence, we have the below equation
![(7)/(8) x= 6](https://img.qammunity.org/2019/formulas/mathematics/middle-school/oncuct9uzgwmqpixts6hgwngn9v9zf3fmv.png)
Now, in order to solve for x, we will divide 6 with 7/8. So, we have to divide.
![x=(6)/(7/8) \\ \\ x=(48)/(7) \\ \\ x=6.9](https://img.qammunity.org/2019/formulas/mathematics/middle-school/9tjfdka9veo53wveyt2hvmm31om0ayqrs2.png)
Hence, we can pour 7 glass of water. But the 7th glass is not full of water. It is partially full.
