Answer 2

Answer:

∴ $125$% of $12$ is $15$.

Step-by-step explanation:

• In context with question asked,
• We have to find the percentage of $12$ which is $15$.
• Let, $x$ be the percentage of $12$ which is $15$.
• The equation is,

       $x$% of $12=15$

      ∴ $\frac{x}{100} \times 12=15$

            ∴ $\frac{12x}{100} =15$

• Transpose $100$ to other side, we get

               ∴ $12x=15\times 100$

               ∴ $12x=1500$

• Transpose $12$ to other side, we get

                 ∴ $x=\frac{1500}{12}$

                 ∴ $x=125$%

• ∴ $125$% of $12$ is $15$.
