HELP PLS AND HURRY

Monica spent 3/5 hours listening to tapes of Beethoven and Brahms. She spent 2/7 hours listening to Beethoven. How many hours were spent listening to​ Brahms?

Answer 1

she spent 2/7 hours

Answer 2

she spent 11/35 hours

Explanation:

first we change the denominator to its lcm, which is 35.

second, change its numerator so, 3/5 become 21/35 and 2/7 become 10/35.

then subtract, 21-10=11

so the answer is 11/35
