1/3 +1/6 in fraction form<br>​
victus00 [196]

\Large\texttt{Answer}

\bf{\cfrac{1}{2}}

\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}

\Large\texttt{Process}

Do you remember that we cannot add fractions when they have unlike denominators? We can onyl add fractions as long as they have the same denominator!

So here's the big idea: fractions must have the same denominator.

If we multiply the first fraction by 2, then both fractions will have the same denominator. *

* <em>Why 2??</em>

<em />

-  Because:

We need to find the least common multiple of 3 and 6, which is 6. Next, what should 3 be multiplied by to result in 6? That's right, 2.

Also, we can only multiply the denominator by 2 as long as we multiply the numerator by 2!

So that's why we multiply the whole fraction by 2

\bf{\cfrac{1\times2}{3\times2}+\cfrac{1}{6}}

Watch what happens

\bf{\cfrac{2}{6}+\cfrac{1}{6}}

Add the numerators

\bf{\cfrac{2+1}{6}}

\bf{\cfrac{3}{6}}

Simplifying the fractions

\bf{\cfrac{3\div3}{6\div3}}

\bf{\cfrac{1}{2}}

Hope that helped
