Chapter 2: Q11. (page 86)

Evaluate the following equation and check the solution is correct or not:
$\frac{a}{36} = \frac{4}{9}$

Short Answer

Expert verified

The solution of the equation $\frac{a}{36} = \frac{4}{9}$ is $a = 16$ .

Step by step solution

Step 1. Given information.

The given equation is $\frac{a}{36} = \frac{4}{9}$ .

Step 2. Write the concept.

In an equation, the variable represents the number that satisfies the equation.

To solve an equation means to find the value of the variable that makes the equation true.

If an equation is true and the same number is added to each side of the equation, then the resulting equivalent equation is also true.

Step 3. Solve the equation.

The equation $\frac{a}{36} = \frac{4}{9}$ can be solved below:

$\frac{a}{36} = \frac{4}{9}$

Multiply both sides by 36,

$\frac{a}{36} \times 36 = \frac{4}{9} \times 36 a = 4 \times 4$

So,

$a = 16$

Step 4. Check the solution.

Take the equation $\frac{a}{36} = \frac{4}{9}$ .

Substitute $a = 16$ on the right-hand side of the equation.

$\frac{a}{36} = \frac{4}{9} \frac{16}{36} = \frac{4}{9} \frac{4}{9} = \frac{4}{9}$

This shows that, $a = 16$ is the solution of the given equation.
