Answer:

Refer the attached figure.

Step-by-step explanation:

Given : Fraction \frac{1}{3}+\frac{1}{4}

To find : Draw a fraction bar for the sum and tell why a common denominator is needed ?

Solution :

Fraction \frac{1}{3}+\frac{1}{4}

We need a common denominator because if two fractions have different denominators, then we have to take an extra step before we can add or subtract them to make calculation easier.

So, \frac{1}{3}+\frac{1}{4}=\frac{4+3}{12}

\frac{1}{3}+\frac{1}{4}=\frac{7}{12}

Now, Refer the attached figure for picture of fractions.
