Subtracting Fractions Using a Number Line

This video tutorial demonstrates how to subtract fractions using a number line. It begins with an introduction to the concept and then provides two examples: subtracting 8 1/5 from 3 4/5 and subtracting 37 7/12 from 18 11/12. The video emphasizes using benchmark numbers and visualizing the subtraction process on a number line to simplify the calculation.

What is the first step in subtracting fractions using a number line?

• Add the fractions first

• Jump to the nearest whole number

• Start with the number you are subtracting
