It is easier to perform the operations if you convert the mixed fractions into improper fractions.
For point 1. Make the mixed fractions improper first
![7(1)/(3)=(3\cdot7+1)/(3)=(21+1)/(3)=(22)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/dt9j3q903u8nwd7qkru37h4vbuzn3m5ar7.png)
![2(2)/(11)=(11\cdot2+2)/(11)=(22+2)/(11)=(24)/(11)](https://img.qammunity.org/2023/formulas/mathematics/college/z7g4xz3b3itpvjscpyiv516qqdbdd3chlr.png)
Now, the multiplication of fractions is done like this
![(a)/(b)\cdot(c)/(d)=(a\cdot c)/(b\cdot d)](https://img.qammunity.org/2023/formulas/mathematics/college/asg3h7ljy9xgj765sx8tttli27lensxrqw.png)
Then, you have
![7(1)/(3)\cdot2(2)/(11)=(22)/(3)\cdot(24)/(11)=(528)/(33)=16](https://img.qammunity.org/2023/formulas/mathematics/college/aeecdwaw3juyog6cnfpgcdt06dryjx996u.png)
For point 2.
![6(2)/(3)=(3\cdot6+2)/(3)=(18+2)/(3)=(20)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/17xkjspbda9zyg2ybfq4443ifvb9n6x0oe.png)
Now multiplying the improper fractions you have
![(3)/(5)\cdot6(2)/(3)=(3)/(5)\cdot(20)/(3)=(60)/(15)=4](https://img.qammunity.org/2023/formulas/mathematics/college/pba91vco95w94i7xgi394wu6nw3qpjm47m.png)
Finally for point 3.
![4(1)/(5)=(5\cdot4+1)/(5)=(20+1)/(5)=(21)/(5)](https://img.qammunity.org/2023/formulas/mathematics/college/xktskkih3bt0zh6auep6wgdgzntlbrprqb.png)
![1(1)/(14)=(14\cdot1+1)/(14)=(14+1)/(14)=(15)/(14)](https://img.qammunity.org/2023/formulas/mathematics/college/m7g7eztxced2gtbhzdz9qp69qd0clrp8rm.png)
Now multiplying the improper fractions you have
![\begin{gathered} 4(1)/(5)\cdot1(1)/(14)=(21)/(5)\cdot(15)/(14)=(315)/(70)=(35\cdot9)/(35\cdot2)=(9)/(2) \\ 4(1)/(5)\cdot1(1)/(14)=(9)/(2) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/wqmsuz237yxa7eu65uipqg9s326gs15bi0.png)
