Question

I cant figure out 1/9 x 81/1 in my math book

Answer 1

9

Explanation:

Simplify before multiplying to make things easier.

`(1)/(9)`*
`(81)/(1)`

you can cross-simplify 9 and 81, which simplifies to:

`(1)/(1)`*
`(9)/(1)`

`(1)/(1)` is equivalent to 1 and
`(9)/(1)` is equivalent to 9, so all you're really doing is multiplying 9*1

9*1 = 9

so 1/9 * 81/1 is just 9.

Answer 2

Answer: 9

Explanation:

1/9 x 81/1

1x81=81

9x1=9

= 81/9

=9
