Answer 2

Answer:

Missing number is $25$ . $\frac{2}{5}$ of $25$ is $10$ .

Step-by-step explanation:

To find : missing number .

Given : $10$ is  $\frac{2}{5}$  of a number  

Solution :

• As per given data we know that $10$  is $\frac{2}{5}$ of a number   .
• Let , number be $x$ .
• According to given condition we write as , $\frac{2}{5}$ of $x = 10$
• Using transposition method , we find the value of $x$ ,by transposing constant at RHS and leaving variable at LHS  .

• $\frac{2}{5}$ of $x = 10$  

        $\frac{2}{5} \times x= 10 \\\\x =10 \times \frac{5}{2} \\\\x = 5\times 5\\\\x = 25$
