Answer:
6.25<6.34<6.84<8.15<8.3<9.142
Step-by-step explanation:
The best way to compare these numbers is to convert all these numbers into the same form either fraction or decimal.
I will convert all the numbers into decimal.
![6.84 \\8(5)/(7) \\6.34\\6(1)/(4) \\8(3)/(10) \\ 8.15](https://img.qammunity.org/2019/formulas/biology/middle-school/hmlj40reo0llzzl6y35skfe48xrn5du8qu.png)
![8(5)/(7) \\= (64)/(7) \\= 9.142](https://img.qammunity.org/2019/formulas/biology/middle-school/cr8n0cyny2u9jxat0gibrltqq5096kc74a.png)
![6(1)/(4) \\= (25)/(4) \\= 6.25](https://img.qammunity.org/2019/formulas/biology/middle-school/v3tsc5na97w2v1u6hibnt2p4hp65w3lq01.png)
![8(3)/(10) \\= (83)/(10) \\= 8.3](https://img.qammunity.org/2019/formulas/biology/middle-school/hq2npcezwkje2mr8fsftvhze7cx4xk8uft.png)
On arranging all the decimals numbers from in ascending order, we get -
![6.25<6.34<6.84<8.15<8.3<9.142](https://img.qammunity.org/2019/formulas/biology/middle-school/sp3mu8ft3vflcejbeldr595vxvn0esxgue.png)
