What number best completes both equations? 5/7÷1/3=? ?×1/3=5/7

Nat2105 [25]

Consider the given equations:

The first equation is as:

$\frac{5}{7} \div \frac{1}{3} = ?$

So, $\frac{5}{7} \div \frac{1}{3}$

= $\frac{5}{7} \times \frac{3}{1}$

Multiplying the given fractions, we get as

= $\frac{15}{7}$

Now, consider the second equation as:

$? \times \frac{1}{3} = \frac{5}{7}$

Multiplying by '3' to both the sides of the equation, we get

$? \times \frac{1}{3} \times 3 = 3 \times \frac{5}{7}$

$? = \frac{15}{7}$

So, the number which best completes both the equations is $\frac{15}{7}$ .
