Rounding Fractions to 0 or 1 on a Number Line

In this video, Mr. J explains how to round fractions between zero and one to either zero or one using number lines. The video covers four examples: three-fourths, two-fifths, four-sevenths, and one-third. The key rule emphasized is to round up if the fraction is greater than or equal to a half. The video also highlights the importance of understanding the concept of approximation when rounding fractions.
