It is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.
<h3>
Division of whole numbers</h3>
When the numerator and denominator of improper fractions are in whole number form, it makes the division a lot easier.
<u>For example</u>;
what is the simplest form of 0.1/0.2?
To obtain the simplest form of the above function, we multiple the numerator and denominator by 10.
= (0.1 x 10)/(10 x 0.2)
= 1/2
<u>Note:</u> introducing factor of 10 to both numerator and denominator has not changed the function.
Thus, it is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.

Step-by-step explanation:
Given that an advisor to the mayor of a large city wants to estimate, within 3 minutes, the mean travel time to work for all employees who work within the city limits.
Let X be the random variable denoting the time for employees to travel within city limit
Std dev of X 
For 95% confidence interval Z critical 1.96 is used because population std dev is known
Margin of error 
i.e. 
where n is the desired sample size.
Simplify to get
Hence atleast 64 employees should he poll
Answer:

Step-by-step explanation:
Exponents are expressed as numbers or variables in superscript above a base number. When the exponent is equal to or greater than 2, it directs how many times the base number is to be multiplied. The numbers 1 and 0 are special exponents, and negative integers as exponents stand for reciprocal values.
