Lola rode her bike for 7/10 of an hour on Saturday, and 3/5 of an hour on Sunday.

How much longer did she ride her bike on Saturday and Sunday?

She rode 1/10 of an hour more on Saturday

Step-by-step explanation:

Take the time she rode on Sunday and subtract that from Saturday

7/10 - 3/5

Get a common denominator

7/10 - 3/5*2/2

7/10 - 6/10

1/10

She rode 1/10 of an hour more on Saturday
