Verified answer
Given:
[tex] \frac{2}{3} + \frac{1}{7} [/tex]
To find:
Addition
Solve:
[tex] \frac{2}{3} + \frac{1}{7} [/tex]
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;
[tex] \frac{2}{3} = \frac{2 \times 7}{3 \times 7} = \frac{14}{21} [/tex]
[tex] \frac{1}{7} = \frac{1 \times 3}{7 \times 3} = \frac{3}{21} [/tex]
Now all the denominators are same.
Now we plus the fractions.
[tex] \frac{14}{21} + \frac{3}{21} = \frac{17}{21} [/tex]
Hence, the required fraction is 17/21.
