Ryan finish his math assignment in 1/5 hours. then he completed his history assignment in 3/4 hours. what was the total amount of the time ryan's band doing these two assignments?

For this problem, we need to find the GTD or greatest common denominator.

So we see we have 1/5 and 3/4.

To get the GTD lets multiply 5 and 4 which gets us 20.

Now we have to multiply 1 by 4 which gets us 4. And we also need to multiply 3 by 5 which gets us 15.

Now we set up the fractions.

4/20 and  15/20

Now we can easily add the two fractions!

19/20

(Im desperate for brainliest answer so I can get the next rank plz notice me senpai)

32.10 is the correct answer
