Vocabulary

Fraction: In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.

Decimal: A decimal is a way of writing a number that is not whole. Decimal numbers are 'in between' numbers. For example, 10.4 is in between the numbers 10 and 11. It is more than 10, but less than 11.

Percentage: In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

45/100 = 45% 18/100 = 18% 79/100 = 79%
