If the units of the two numbers of a ratio are not the same, we need to unify them.
(a) 12:7 = 
(b) 7:12 = 
(c) 5 cm : 40 cm = 
(d) 1 kg = 1000 g, then
83 g to 1 kg = 83 g to 1000 g = 
Write the following ratios as fractions. (You don’t need to simplify)
(a) 12:7
(b) 7 to 12
(c) 5 cm : 40 cm
(d) 83 g to 1 kg
