Consider the given equations:
The first equation is as:
[tex]\frac{5}{7} \div \frac{1}{3} = ?[/tex]
So, [tex]\frac{5}{7} \div \frac{1}{3}[/tex]
= [tex]\frac{5}{7} \times \frac{3}{1}[/tex]
Multiplying the given fractions, we get as
= [tex]\frac{15}{7}[/tex]
Now, consider the second equation as:
[tex]? \times \frac{1}{3} = \frac{5}{7}[/tex]
Multiplying by '3' to both the sides of the equation, we get
[tex]? \times \frac{1}{3} \times 3 = 3 \times \frac{5}{7}[/tex]
[tex]? = \frac{15}{7}[/tex]
So, the number which best completes both the equations is [tex]\frac{15}{7}[/tex].
