Question

Some more fractions, with common denominators

Answer 1

`(5)/(6)-(1)/(9) = (45)/(54) -(6)/(54) = (13)/(18)`

Explanation:

An easy way to find a common denominator is to multiply the denominators against each other, like this:

`((9)/(9))(5)/(6)-(1)/(9) ((6)/(6))`

Now, simplify:

`(45)/(54)-(6)/(54)`

Then, subtract:

`(39)/(54)`

Simplify:

`(13)/(18)` (Divide numerator and denominator by 3)

Hope this helps!!
