What model shows that .4 is greater than .02?

To demonstrate that 0.4 is greater than 0.02, you can use a number line model. On the number line, 0.02 is located close to the origin, while 0.4 is positioned further to the right, indicating that it is a larger value. Alternatively, you can express both numbers as fractions: 0.4 can be represented as 40/100 and 0.02 as 2/100. Since 40/100 is greater than 2/100, this further confirms that 0.4 is greater than 0.02.
