Answer 2

Answer:

Hence,required ans is $\frac{9}{56}$.

Step-by-step explanation:

Given-

$\frac{7}{8} -\frac{5}{7}$

We have to find the fraction.  

Solution-

$\frac{7}{8} -\frac{5}{7}$

we multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction.

By changing the denominators to the product of both the denominators.

$=\frac{7\times\\7}{8\times\\7} - \frac{5\times\\8}{8\times\\7\\}$

$=\frac{49}{56} - \frac{40}{56}$

$=\frac{49-40}{56}$

$=\frac{9}{56}$

Hence,required ans is $\frac{9}{56}$
