Gavin had 20 minutes to do a three-problem quiz.
He spent 9 3/4 minutes on problem 1.
He spent 3 4/5 minutes on problem 2.
How much time did he have left for problem 3?
We need to add the time spent on problem 1 and problem 2 and then subtract the sum from the total time.
![20-(9\frac{3}{4}+3\frac{4}{5})](https://tex.z-dn.net/?f=20-%289%5Cfrac%7B3%7D%7B4%7D%2B3%5Cfrac%7B4%7D%7B5%7D%29)
Simplify the above fraction

Let us write the answer in mixed number
![\frac{129}{20}=6\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B129%7D%7B20%7D%3D6%5Cfrac%7B9%7D%7B20%7D)
Finally, convert the fractional part to seconds by multiplying the fractional part by 3
![6\frac{9}{20}=6\frac{27}{60}](https://tex.z-dn.net/?f=6%5Cfrac%7B9%7D%7B20%7D%3D6%5Cfrac%7B27%7D%7B60%7D)
This means that there are 6 minutes and 27 seconds are left for problem 3.
The answer I got was 417/50 hope this helps you
