Chapter 12, Problem 5GR

To determine

To find: the solution of the fractions in simplest form.

Answer to Problem 5GR

The solution to the fraction is $\frac{\text{13}}{2}\text{ or }6.5$ .

Explanation of Solution

Given:

  $\frac{\text{6+4+7+9}}{\text{4}}$ .

Concept used:

The abbreviation BODMAS can be elaborates as:

  $\text{B=bracket},\text{ O=order, D=division, M=multiplication, A=addition and S=subtraction}\text{.}$

Let the denominator as it is and add or subtract the numerator.

If denominators of two factors doesn’t contain common factor then the L.C.D will be multiplication of two denominators.

If denominator of two factors contain common multiple then the denominator will be common to the least or lowest common multiple.

Calculation:

  $\frac{\text{6+4+7+9}}{\text{4}}$ .

Frist make the bracket to numerator so that $\text{Bodmas}$ can be apply:

  $\begin{array}{l}\frac{\left(6+4+7+9\right)}{4}=\frac{26}{4}.\\ \Rightarrow \frac{\text{13}}{2}.\end{array}$

In decimal form it can be written as:

  $\text{6}\text{.5}$ .

Hence, the solution to the fraction is $\frac{\text{13}}{2}\text{ or }6.5$ .
