a. A graph of the numbers 13/8 and 3/8 is shown on the number line in the picture below.
An inequality that is true for the numbers is 13/8 > 3/8.
In Mathematics and Geometry, a number line is a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values that are located at equal intervals along its length.
This ultimately implies that, every number line would primarily increase in numerical value towards the right from 0 and decrease in numerical value towards the left from 0.
Based on the information provided about the numbers, we have the following:
x = 13/8
x = 3/8
Since the number 3/8 is to the left of zero while 13/8 is to the right of zero, we can logically deduce that 13/8 is greater than 3/8. Therefore, the inequalities that are true for the numbers can be written as follows;
13/8 > 3/8.
3/8 < 13/8.
