we are given that Lydia studied 3/4 of an hour and then 1/4 of an hour. To determine the total number of time that he spent studying we need to add both decimals, like this:


n=(3)/(4)+(1)/(4)

Where "n" is the total time.

Adding both decimals together:


n=(3+1)/(4)=(4)/(4)=1

Therefore, Lydia spent 1 hour.
