How to Display Percentages on Number Lines - You know what number lines are, right? Just like different math tools, a number line is a tool that is used for solving questions easily. Here is a quick review of what number lines are! The placement of numbers on a straight line in a series that starts from the smallest number and goes up to the biggest number is known as a number line. The numbers on the number line don't always have to start from zero, the main rule of the number line is that the numbers are always placed in an order. Just like we place numbers on a number line, percentages are also placed in the same way. Starting from the smallest value, the positives are placed on the right side of the number line while the negative value is placed on the left side of the number line. The worksheets and lessons can be used to show you a relative position of a percentage value expressed on a number line.
