Chapter 4, Problem 17CR

To determine

To write the fraction in simplest form $\frac{4}{18}$

Answer to Problem 17CR

  $\frac{2}{9}$

Explanation of Solution

Given information:

Expression $\frac{4}{18}$

Formula Used: Factorization

Calculation:

Here, break both the numerator & denominator into its factors respectively.

So, 4 may be written as $2\times 2$

And 18 may be written as $3\times 3\times 2$

The fraction is revised as follows-

  $=\frac{2\times 2}{3\times 3\times 2}$

As can see that2is available in both numerator & denominator. So these values cancel out and have-

  $=\frac{2}{3\times 3}$

Hence,

  $=\frac{2}{9}$

Conclusion-

  $=\frac{2}{9}$
