Answer 2

Given:

$\frac{2}{3} + \frac{1}{7}$

To find:

Addition

Solve:

$\frac{2}{3} + \frac{1}{7}$

As you can see denominators are not same. So, Take LCM of denomination to LCM the denominators same.

LCM of 3 and 7 is 3×7=21

Now;

$\frac{2}{3} = \frac{2 \times 7}{3 \times 7} = \frac{14}{21}$

$\frac{1}{7} = \frac{1 \times 3}{7 \times 3} = \frac{3}{21}$

Now all the denominators are same.

Now we plus the fractions.

$\frac{14}{21} + \frac{3}{21} = \frac{17}{21}$

Hence, the required fraction is 17/21.
