Answer:

Second number = 12% of the first number

Step-by-step explanation:

Let the second number be a and the second number be b.

Given that the sum of two numbers is \frac{28}{25} of the first number.

Thus, sum of two numbers = a + b

Now, we understand that,

a+b=\frac{28}{25} \times a

Now, bring the denominator (25) to the left hand side.

25(a+b)=28a

Multiply 25 with(a+b),

25 a+25 b=28 a

28 a-25 a=25 b

\therefore 3 a=25 b

Hence, the second number b=\frac{3 a}{25} of the first number

∴ Second number =\frac{\frac{3 a}{35}}{a} \times 100 \% of the first number = 12% of the first number
