Question

What is `3/11 -:5/7`?

Answer 1

`21/55`

Explanation:

`3/11 div 5/7 = (3/11) / (5/7)`

Flip `5/7` and change the symbol from `div` to `xx`

`3/11 xx 7/5`

Multiply straight across, which gets you `21/55`.

Answer 2

`21/55`

Explanation:

When dividing fractions, you always flip the second fraction (numerator becomes denominator, denominator becomes numerator) and you multiply the two fractions.

`3/7*7/5`

So now you multiply the numerators by each other and the denominators by each other:

`(3*7)/(11*5)`

`21/55`

Hope this helps!
