The video tutorial by Mr. J explains repeating decimals, which are decimals that continue indefinitely without terminating. It covers how repeating decimals occur during division when a clean zero is never reached. The video provides two examples: dividing 14 by 9 and converting the fraction 3/11 into a decimal, both resulting in repeating decimals. The tutorial also demonstrates how to express repeating decimals using bar notation. The video aims to enhance understanding of repeating decimals and their formation through division.

What is a repeating decimal?

• A decimal that ends after a few digits

• A decimal that repeats a pattern indefinitely

• A decimal that changes its pattern

• A decimal that is always less than 1
