Karen spent 7/10 hour reading and 3/5 hours writing in her journal how much longer did karen spend reading than writing in her journal

1/10

Step-by-step explanation:

From the question, we are informed that Karen spent 7/10 hour reading and 3/5 hours writing in her journal.

To calculate how much longer karen spent reading than writing in her journal, we have to subtract 3/5 from 7/10. This will be:

= 7/10 - 3/5

Note that the lowest common multiple of 5 and 10 is 10.

= 7/10 - 6/10

= 1/10

Therefore, the answer is 1/10
