Chapter 1.1, Problem 28PPS

To determine

To evaluate: the given expression

Answer to Problem 28PPS

The numerical value of the given expression is $2$

Explanation of Solution

Given:

  $\frac{5+9}{10-3}$

Calculation:

Given the expression $\frac{5+9}{10-3}$ , rewrite this as division expression.

  $\frac{5+9}{10-3}=\left(5+9\right)÷\left(10-3\right)$

First solve the two brackets

  $5+9=14$

And

  $10-3=7$

Therefore, the expression reduces to

  $\frac{5+9}{10-3}=\left(5+9\right)÷\left(10-3\right)=14÷7$

Therefore the numerical value of the given expression is $14÷7=2$

  $\frac{5+9}{10-3}=2$

Conclusion:

Therefore the numerical value of the given expression is $2$
