Explanation:
In order to find the answer to this question you need to remember that all numbers have a invisible denominator that comes into effect when you are doing anything with fractions that invisible denominator is 1, and of course remember KCF (Keep, Change, Flip) while solving this problem.
![20/(15)/(16)](https://img.qammunity.org/2022/formulas/mathematics/college/ksz1grd7debg0v8io4klq9eb50z1k129gs.png)
![20=(20)/(1)](https://img.qammunity.org/2022/formulas/mathematics/college/hic0jk4pwc50vwh1wrx89bbixf6n2adik8.png)
![(20)/(1) /(15)/(16)](https://img.qammunity.org/2022/formulas/mathematics/college/nb7vezbfmmntpfg1hoaujwhybw8xdal0b4.png)
Use KCF:
![(20)/(1) *(16)/(15)](https://img.qammunity.org/2022/formulas/mathematics/college/4nucnr1dbkqzj685qvioixt6enun0liu0s.png)
Multiply:
![20*16=320](https://img.qammunity.org/2022/formulas/mathematics/college/xjxj7daejnpl5zqryqmw7a1vqhlomrmm48.png)
![1*15=15](https://img.qammunity.org/2022/formulas/mathematics/college/v6q3gehoxdgsl0ku0jns2wbtxn738vpn82.png)
![=(320)/(15)](https://img.qammunity.org/2022/formulas/mathematics/college/yddidhh0mzmjyhqm3j2wg3za138l620uwq.png)
Simplify:
![320/5=64](https://img.qammunity.org/2022/formulas/mathematics/college/5oguyk94a4ou65515ydtq22yuap8eca4fn.png)
![15/5=3](https://img.qammunity.org/2022/formulas/mathematics/college/iq9a6n4xa1g64831rzjxi4dumtpgizh3ph.png)
![=(64)/(3)](https://img.qammunity.org/2022/formulas/mathematics/college/m2e8na9pev1j5ytq3orq9i5a58pb6hnmo6.png)
Convert into mixed number:
![64/3=21.33333=21](https://img.qammunity.org/2022/formulas/mathematics/college/7alyzimpl36i4g0md8uxdsesooudgxah1i.png)
![64-(3*21)=1](https://img.qammunity.org/2022/formulas/mathematics/college/nywqh700nbovir7vr8g05jz2k1mgqlhgpu.png)
![=21(1)/(3)/(64)/(3)](https://img.qammunity.org/2022/formulas/mathematics/college/cfbv77nx5xfp71kpgepxvxvp8mjpfpmhlg.png)
Hope this helps.
