7) Jupiter complets about 2 2/5 rotation every 24 hours (an earth day). How many rotation does jupiter complete in one earh week?

(24x7)x2 2/5

24x7=168

168x2 2/5

168x2=336

336/5=67 1/5

8) A sailboat is sailing at 81/2 km. If the weather conditions and the current do not change, how far will the sailboat travel in 11/3 hour?

8 1/2 x 1 1/3

8x2+1=17 3x1+1=4

17/2 x 4/3=68/6

= 11 2/6

10) It takes 3/5 of a tank of gas to get to work and back each day. How much gas it used over 5 work days?

3 1/2x4x5

7/2x4/5

4/2 x 7/5=14/5
