Question

Monica spent 3/4 hours listening to tapes of Beethoven and Brahms. She spent 1/5 hours listening to Beethoven . How many hours were spent listening to Brahms

Answer 1

Monica spent 0.55 hours listening to Brahms.

Explanation:

We are given the following in the question:

Amount of time spent listening to tapes of Beethoven and Brahms =

`=(3)/(4)`

Amount of time spent listening to Beethoven =

`=(1)/(5)`

Total time spent listening to Brahms =

Amount of time spent listening to tapes of Beethoven and Brahms - Amount of time spent listening to Beethoven

`=(3)/(4)-(1)/(5)\\\\=(15-4)/(20)\\\\=(11)/(20)\text{ Hours}\\\\=0.55\text{ Hours}`

Thus, Monica spent
`(11)/(20)\text{ hours}` listening to Brahms.
