math? 3 divided by one third is 9.
Was that your question?

Bc dividing a fraction is multiplying the inverse
not sure if that's the way to explain it, but that's what I was taught.

Dividing by fractions is easy as pie. Flip the divisor and multiply.

Division is multiplication of the reciprocal. Any second grader can tell you that.

whenever you divide a number by a fraction you can also multiply that number by the reciprocal of the fraction. therefore 3/ 1/3 is the same as 3*3.

By adding the parenthesis you changed the problem... which changed the outcome...
As it is originally written, you subract the 3 from 9 before you divide by 1/3rd...
