this is clearly a trick question. 20 plus 20 plus 20 is equal to 60 and there is 60 minites in 1 whole hour so 20 plus 20 plus 20 is equal to 1.
109 you can plus like this: (19+1)+20+20+(1+1+18)+4+25
In fact, 1/10 + 1/10 + 1/20 + 1/4 + 1/2 is equal to 1.1/10= 2/20 1/4= 5/20 1/2= 10/202/20+2/20= 4/20+1/20=5/20+5/20=10/20+10/20=20/2020/20=1
