Rational Numbers

by | Sep 2, 2020

This week, in all math classes, we have been focusing on identifying and classifying rational numbers.  Students must have a firm understanding of sets and subsets of real numbers to make a connection with real-world situations.

Rational numbers are those of the p / q form, where q is not equal to zero. For example, all integers are rational numbers, since each integer can be written as follows in the form of p / q.

  • Integers are whole numbers (like 1, 2, 3, and 4) and their negative counterparts (like -1, -2, -3, and -4).
  • Fractions are numbers that are expressed as ratios. A fraction is a part of a whole.
  • Fractions have numerators, which are the numbers on the top of the fraction that show the parts taken from the whole.
  • Fractions also have denominators, which are the numbers on the bottom of the fraction that show how many parts are in the whole.
