Question

Perform the indicated operation. Round the result to the nearest tenthand then to the nearest hundredth. Separate your answers by a comma.14.357 (-2.625)

Answer 1

Given the operation:

$14.357-(2.625)$

You need to follow these steps in order to solve the exercise:

1. Multiply signs by applying the Sign Rules for Multiplication:

$\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ -\cdot+=- \\ +\cdot-=-_{} \end{gathered}$

Then:

$=14.357-2.625$

2. Subtract the numbers:

$=11.732$

3. Round it to the nearest tenth:

- Notice that the digit to the right of the digit in Tenth Place is:

$3$

- Since:

$3<5$

You must round down. The digit in the Tenth Place (7) stays the same:

$\approx11.7$

4. Round the result obtained in Step 2 to the nearest hundredth;

- Notice that the digit to the right of the digit in Hundredths Place is:

$2$

- Since:

$2<5$

The digit in the Hundredths Place (3) stays the same:

$\approx11.73$

Hence, the answers is (the results rounded are separated by a comma):

$\approx11.7,\text{ }11.73$
