For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:
![8 \frac {3} {4} = \frac {4 * 8 + 3} {4} = \frac {32 + 3} {4} = \frac {35} {4}](https://tex.z-dn.net/?f=8%20%5Cfrac%20%7B3%7D%20%7B4%7D%20%3D%20%5Cfrac%20%7B4%20%2A%208%20%2B%203%7D%20%7B4%7D%20%3D%20%5Cfrac%20%7B32%20%2B%203%7D%20%7B4%7D%20%3D%20%5Cfrac%20%7B35%7D%20%7B4%7D)
Thus, each student takes
minutes.
If there are 9 students in the recital then we have:
minutes.
Thus, the recital lasts at least 78.75 minutes.
Answer:
The recital lasts at least 78.75 minutes.
The lest common multiple is 26. If you do multiples of each number
13:13,26
26: 26
Both of their lest common multiples would be 26
