Note the following conversions before seeing the solutions:
1m = 100 cm
1 mi = 5280 ft
1 lb = 16 oz
You simply convert into either units to obtain the same units in the numerator and denominator!
1. 60 cm/(100 cm)
==> 3/5
2. 2 mi/(3000 ft * (1 mi/5280 ft))
==> 2 mi/(25/44 mi)
==> 2 mi * (44/25 mi)
==> 88/25
3. 2 lb/20 oz
==> (2 lb * 16 oz/lb)/20 oz
==> 32 oz/20 oz
==> 8/5
4. 20 oz/(4 lb * 16 oz/lb)
==> 20 oz/64 oz
==> 5/16
I hope this helps!
