Answer:
Explanation:
Alright, lets get started.
![8(1)/(2)-3(1)/(?)=5(3)/(12)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/4e4ftm4hwtp863y8r32a4xs4ibm9b8gmjj.png)
These are mixed number given.
Suppose the complete mixed number of second place is x.
Converting mixed numbers into fractions.
![(17)/(2)-x=(63)/(12)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zkarn5wqytrc7fxfkrqb051v3opsebtpeo.png)
Adding x in both sides
![(17)/(2)=x+(63)/(12)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8bewmdwyqgql9wedqc00ybdvdea52nv359.png)
![x=(17)/(2)-(63)/(12)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/p5ejaux9vak6t4qoba65sd4i7wdjzuaiok.png)
Making common denominator
![x=(102)/(12)-(63)/(12)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/1vdzm815va5n08ki1n3327ei2u7uwc4j1x.png)
![x=(39)/(12)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/r2cjur5sijmywri6a3o7gtchypx3fwb8n4.png)
![x=(13)/(4)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/z28shh71y2yc8s4rtt2rntpt94wykzkds5.png)
In mixed number form:
![x=3(1)/(4)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/4w3m93aqz57kjsj520hhrbf4elwjke9vws.png)
So comparing with given equation, the '?' sign will be equal to 4.
Hence the answer is 4 : Answer
Hope it will help :)
