Answer 2

Answer:

$\text{The fraction is }\frac{7}{8}$

Step-by-step explanation:

$\text{we have to find the fraction of }\frac{4}{7}\text{ which must be added to itself to make the sum }\frac{15}{14}$

Let x be the fraction of $\frac{4}{7}$

⇒ $x\times \frac{4}{7}+\frac{4}{7}=\frac{15}{14}$

$\frac{4}{7}(x+1)=\frac{15}{14}$

$x+1=\frac{15}{14}\times \frac{7}{4}$

$x=\frac{15}{8}-1=\frac{7}{8}$

$\text{Hence, the fraction is }\frac{7}{8}$
