Jason spends 3 1/12 hours biking and 2 1/3 hours at the mall. how much less time does jason spend at the mall compared to biking?

We must find the difference between 3 1/12 and 2 1/3. So we can first subtract 3 from 2 and we earn 1 whole number. Next we must subtract  1/12 and 1/3. This is the same as 3/36-12/36, which is -9/36 or -1/4. Since we can't have -1/4 we must subtract 1/4 from 1 and earn 3/4 as our answer.

Hope this helps! <3

rick would give her the best deal as he will charge $8.88 per hour
