Chapter 6.2, Problem 67CCR

To determine

Calculate the variable in the equation and also check it.

Answer to Problem 67CCR

The value of $k$is $\frac{1}{5}$ .

Explanation of Solution

Given: It is given in the question that the expression are $20=100k$ .

Concept Used:

In this, use the concept of doing the same operation on the both sides of the equation.

Calculation:

  $\begin{array}{l}20=100k\\ \frac{20}{100}=\frac{100k}{100}\\ \frac{1}{5}=k\\ k=\frac{1}{5}\end{array}$ (Dividing)

Check:

Right Hand Side: $100k=100\times \frac{1}{5}=20$ = Left Hand Side

Conclusion:

The value of $k$is $\frac{1}{5}$ .
