Chapter 7.4, Problem 59S

To determine

To solve and check: the given equation

Answer to Problem 59S

The required answer is $n=\frac{1}{4}$

Explanation of Solution

Given:

  $40n=10$

Calculation:

The expression is $40n=10$ .

The objective is to solve the above proportion.

Simplify the expression as follows

  $\begin{array}{l}40n=10\\ \frac{40n}{40}=\frac{10}{40}\\ n=\frac{1}{4}\end{array}$

Check solution:

Substitute $n=\frac{1}{4}$ in above expression.

  $40\times n=40\times \frac{1}{4}$

= 10 (correct)

Hence, $n=\frac{1}{4}$

Conclusion:

Hence, the required answer is $n=\frac{1}{4}$
