Rational number are numbers which can be expressed in a ratio of two integers. Both numerator and denominator are whole numbers<span>, where the denominator is not equal to zero.</span>
An irrational number<span> on the other hand is a </span>number which cannot be expressed in a ratio of two integers. However there are similarities between them. For example: the product of both irrational numbers of born rational numbers can be rational number, both irrational and rational numbers can be negative and positive, and both can be expressed as a fraction.
Answer:

Step-by-step explanation:
The question relates to dividing a fraction by proper and another fraction
The given expression is presented as follows;

We rearrange the fractions as improper fractions for easier division as follows;


Therefore, we have;


Answer: I think it is -0.4
Step-by-step explanation:
For this case we must factor the following expression:

To factor, we must find two numbers that when added together give -7 and when multiplied by -10.
It is observed that there are not two whole numbers that comply with the aforementioned.
Thus, the following equation applies:

Where:

We replace:

So, the roots are:

Answer:

<h3>
Answer: 8</h3>
Reason:
Replace p with 2 and evaluate.

Think of a cube that is 2 units along each side. It's volume is 2*2*2 = 8 cubic units. Repeated multiplication can be shortened to using exponents.
