Question

Multiply negative three tenths and negative five twelfth

Answer 1

-$\frac{3}{10}$ × -$\frac{5}{12}$
=$\frac{15}{120}$

Note that it is $\frac{15}{120}$ not -$\frac{15}{120}$ since two negatives will cancel each other out. 

Now we need to simplify $\frac{15}{120}$. We do this by dividing by the greatest common factor. I'll use the guess and check method, but there are other methods that you could also use.

$\frac{15}{120}$ ÷ $\frac{15}{15}$
=$\frac{1}{8}$

Your answer would be $\frac{1}{8}$
