Raul spends 90 minutes at guitar lessons every 2 weeks. how many hours does he spend at guitar lessons in 8 weeks? (tip: 60 minutes = 1 hour)

He spent 12 hours practicing Guitar.

First do 90 x 8 = 720. So Raul spent 720 minutes practicing.

Now to solve the hours do 720 / 8 = 12

Hope this helps!

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
