the first on is 1kg/3L  =  0.33333 kg/L

 

You need to change 2 pounds to Kg      

you can use this site for that

https://www.google.com.au/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=convert%20pounds%20to%20kilograms

 

then 7 pints to litres     7/2.11 = 3.3175... L

then do the division and compare the answers.

 

(*You could have done it the other way round if you had wanted to.  You just have to make the units the same.  )

Tortoise A walks 52.0 feet per hour and Tortoise B walks 12 inches per minute. Which Tortoise travels faster? Explain. 

 

12inces1min=1260inches60minutes=1260inches60minutes=1260inches1hour=(1260)/12feet1hour=60feet1hour

 

so that is faster than 52 feet per hour.  :)
