• Fractions consists of two numbers separated by a hyphen. Number listed above the line is called numerator, and under line denominator.
• Fractions where numerator is greater than denominator e.g. 5/4 are correct too. These type of fractions represent number greater than one. They are called improper fractions or heavy top fractions.
• Fractions with numerator less than denominator e.g. 1/2 are called proper fractions.
