Answer 2

To find : difference of rational numbers $\frac{7}{11}- \frac{3}{7}$

Solution:

• To find the difference of given rational numbers we get need to equalize denominators of both the rational numbers. By taking LCM

• Therefore, LCM = $77$

• Now, multiplying numerators of both rational numbers by same number as multiplied by denominators to make LCM.

• Therefore, we get,  $\frac{7}{11}- \frac{3}{7}=\frac{7 \times 7}{77}- \frac{3 \times 11}{77}$

                                                     $= \frac{49 - 33}{77} \\= \frac{16}{77}$

Hence, difference of $\frac{7}{11}- \frac{3}{7}$ is $\frac{16}{77}$ .
