Answer:

Step-by-step explanation:
For example, a sum of a number and 6 is 12.
The number is unknown.
Let the number be x.
We can solve for x (unknown number). Subtract 6 from both sides of the equation.
For this case we have the following definition:
A real number can be a rational number or an irrational number.
The rational numbers are those that can be expressed as the quotient of two integers, such as 3/4, -21/3, 5, 0, 1/2, while the irrational numbers are all the others.
Between 0.1 and 0.11 we have:
Rational number: 105/1000 = 0.105
Irrational number: 01057685429832687
The GCF of 20 and 70 is 10
90=10(7+2) could be used as another related expression
