Explanation:
From the question,the left cup of dip is
![(5)/(6)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/k1ulr704v57tjzp2eybo8uxmo4hd1dog5g.png)
Jim divides 6/7 cup of the left over ,5/6 dip between 3 friends
This implies that,
![((6)/(7)* (5)/(6))/3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qo55nv4vh0c7xho2qbyhbfmi406523zfco.png)
We first simplify what is in the bracket to obtain
![(5)/(7)/ 3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/umfu2p155vk197az9z3m7ucjtf4g58ruk5.png)
we now reciprocate 3 and change the division symbol to multiplication
This implies that,
![(5)/(7)*(1)/(3)= (5*1)/(7* 3)= (5)/(21)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/36kljx2h06jn5twqw5ls2t96kxtslqqh16.png)
Hence each friend of Jim receives 5/21 cup of the left over dip
