Question

Simplify: -5/3 + 7/-18​

Answer 1

Answer:

The Numbers given here are -5/3 and 7/-18.

It is best to turn the negative sign onto the numerator because taking L.C.M would be difficult with a negative denominator.

So, the numbers are -5/3 and -7/18

The denominators are 3 and 18, and the L.C.M of 3 and 18 is 18, because:

3 x 6 = 18

18 x 1 = 18

Now -7/18 doesn't require any change as the denominator is already 18, but -5/3 needs a change. We have to multiply both 3 and -5 with 6 since 3 multiplied with 6 makes 18

So, $\frac{-5*6}{3*6}$  = $\frac{-30}{18}$

So, now we can add. The numbers being -7/18 and -30/18.

Adding,

$\frac{-30+-7}{18}$

=$\frac{-37}{18}$

The answer is -37/18.
