It is 300 + 10 + 1.
Its decimal "expansion" is 30, as in the question. You could express it as 30.000... except that doing so would imply a greater degree of precision.
It is 1/100.
1/9
A decimal expansion means to write out the base 10 digits of a number. Because irrational numbers do not have a closed form, the decimal expansion will always be an approximation. Consider the irrational number pi, which has the following decimal expansion: 3.14159265... Of course there are more digits to pi than that, which is denoted by the "...". It is sadly impossible to list ALL of the digits of an irrational numbers, since if there were a finite number of digits, you could express it as a fraction, which would not be irrational.
In the decimal expansion of , the digit repeats indefinitely.
The decimal expansion of an irrational number is non terminating and non recurring
It is the decimal approximation to the value of the irrational number.
It is 0. As is every digit after the decimal point.
a single unit
Its decimal "expansion" is 30, as in the question. You could express it as 30.000... except that doing so would imply a greater degree of precision.
0.125
569.384 = 71173⁄125
0.5454 repeating
It is 300 + 10 + 1.
It is -35, exactly as in the question.
You carry out long division.
