Ratios
Part to Part
a) five checks to three x's b) 5 checks: 3 x's c) 5 checks/3 x's
NOTE: You need to give the units for each - 5:3 is not enough because what does the 5 represent??
Part to Whole
5: 8
Note that we don't need the units because the order they come in is given in the question - "part to whole for check symbols to all"
Unit Rate: 4 doughnuts/1hr OR 4 doughnuts per hour OR 4 doughnuts/hr
30 hours to drive 600 km
--> 600/100 = 6.
--> This means 600/6 = 100 km
---> 30 hours/6 = 5 hours
