You can put this solution on YOUR website! You can't imagine infinity so to explain it:
Let x be any positive number.
1/x = 0
Put different values of x (x>O)
1/1=1
1/10=0.1
1/100=0.01
1/1000=0.001
..

1/10000000000…….. ~O (Since infinity is a very big number, 1 over infinity would be a very small number so therefore it is approximately 0)
