Remember:
- Every rational number is a terminating or a repeating decimal.
- Convert \(\frac{a}{b}\) by dividing \(a\) by \(b\); a remainder of \(0\) means the decimal terminates.
- A repeated remainder means a repeating decimal, written with a bar: \(\frac{5}{11}=0.\overline{45}\).
- Subtracting a number is adding its opposite: \(a-b=a+(-b)\).
- Multiplying or dividing two numbers with the same sign gives a positive result; with different signs, a negative result.
