Can someone me simplify 1/3 x 1/9? *also, show

*i need because i went on vacation for a month and missed school and i didn't do this at school when i left to go on vacation.

1/3 x 1/9
Change the denominator(bottom half) so that they have the same factors, but when doing this you have to change the top too. 3 x 3 is 9 so the denominator will be 9 for both fractions, then 1 x 3 is 3 so the equation will look like this:
3/9 x 1/9
Then you can multiply
3/9 x 1/9 = 3/9 which can reduce to 1/3 
Hope this helps, it's harder to explain math virtually.

6.4 / 1.6 = 4;
25.6 / 6.4 = 4;

The number pattern is 4 .
