Answer:
![5(1)/(6) < 5(13)/(30) < 5(68)/(90)](https://img.qammunity.org/2021/formulas/mathematics/high-school/ixm8w9jchb2cgyl8v0vx1iy7zuf72ykaet.png)
Explanation:
Represent the friends with A, B and C
![A = 5(13)/(30)](https://img.qammunity.org/2021/formulas/mathematics/high-school/1z7qvb7g8sx3blfuamyec96wx9jsd7moeb.png)
![B = 5(1)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/mchhklvnqv3gbq9hmg26pdyqx60kmcjnhp.png)
![C = 5(68)/(90)](https://img.qammunity.org/2021/formulas/mathematics/high-school/7arl74fg4unsm7959f2xhrhqnbn5wdgn7u.png)
Required
Order from least to highest
First, we convert the given parameters to decimal
![A = 5(13)/(30)](https://img.qammunity.org/2021/formulas/mathematics/high-school/1z7qvb7g8sx3blfuamyec96wx9jsd7moeb.png)
![A = 5 + (13)/(30)](https://img.qammunity.org/2021/formulas/mathematics/high-school/n7h8l5h2x7hkpbxo6pwc9zwrnvq33o7nj1.png)
![A = 5 + 0.43](https://img.qammunity.org/2021/formulas/mathematics/high-school/oduroehbsm46e8jq3ojd2tptqkwcmzgwib.png)
![A = 5.43](https://img.qammunity.org/2021/formulas/mathematics/high-school/2io0ouht7thezhzsnyxcci5qugdqxu91n4.png)
![B = 5(1)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/mchhklvnqv3gbq9hmg26pdyqx60kmcjnhp.png)
![B = 5 + (1)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/ijb805kkdt0eo6jv20i1iyc64de34jzzem.png)
![B = 5 + 0.17](https://img.qammunity.org/2021/formulas/mathematics/high-school/ssz55y8mi0dbs7enrbrtssa3051j9neyab.png)
![B = 5.17](https://img.qammunity.org/2021/formulas/mathematics/high-school/undvumeretskydzk753pz4s9jsatj95o31.png)
![C = 5(68)/(90)](https://img.qammunity.org/2021/formulas/mathematics/high-school/7arl74fg4unsm7959f2xhrhqnbn5wdgn7u.png)
![C = 5 + (68)/(90)](https://img.qammunity.org/2021/formulas/mathematics/high-school/s540fkyl2anz0vm19t69h0t89cev2spgh0.png)
![C = 5 + 0.76](https://img.qammunity.org/2021/formulas/mathematics/high-school/imumt1brssiqdjq48ud9gbs9ms7tl0irad.png)
![C = 5.76](https://img.qammunity.org/2021/formulas/mathematics/high-school/8ntug7230kkopa7wocu1f0p4lo53bq9j56.png)
So, we have:
![C = 5.76](https://img.qammunity.org/2021/formulas/mathematics/high-school/8ntug7230kkopa7wocu1f0p4lo53bq9j56.png)
Order from least to greatest
![C = 5.76](https://img.qammunity.org/2021/formulas/mathematics/high-school/8ntug7230kkopa7wocu1f0p4lo53bq9j56.png)
Replace them with the original values
![C = 5(68)/(90)](https://img.qammunity.org/2021/formulas/mathematics/high-school/7arl74fg4unsm7959f2xhrhqnbn5wdgn7u.png)
Hence, the correct order is:
![5(1)/(6) < 5(13)/(30) < 5(68)/(90)](https://img.qammunity.org/2021/formulas/mathematics/high-school/ixm8w9jchb2cgyl8v0vx1iy7zuf72ykaet.png)
