Create a comparison statement using 4.9 and 4.09

The number 4.9 is greater than 4.09 by 0.81.

This problem can be solved using two methods:

First method: Subtract the small number from the greater one.

Second method: Subtract both numbers in any order and take the absolute value:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
