+130466 It helps if we can reduce before we multiply
9/60 = 3/20
30/60 = 1/2
16/60 = 4/15
So we have
3/20 * 4/15 * 1/2 note something...I can write this as...
3/15 * 4/20 * 1/2 (verify for yourself that this = the previous product) .... and rearranging this, we have....
1/5 * 1/5 * 1/2 = 1/50
See how "cancelling" and "rearranging" makes the multiplication of fractions easier?? (Be careful though, the "rearranging" thing only works with multiplication of fractions....NOT addition)
