Answer:
A, C, D, B
Step-by-step explanation:
Let's find out the approximate digital value of each expression in order to sort them out more easily, and we'll see if we'll need to get more precise afterwards.
The first one is a bit complicated, but let's just mark it as negative something (it's below zero for sure).
The second one is a product of two negative number so it will be a positive number so we can resume that as being 4.5 * 2.3 which will do something around 10.
The third one... is a bit less than 3.5 (3.5 would be 3 and 7.5/15)
[tex]5 \frac{11}{15} - 2 \frac{4}{15} = 3 \frac{7}{15}[/tex]
The fourth one... is exactly 3.5
[tex]3 \frac{3}{20} - (- \frac{7}{20} ) = 3 \frac{3}{20} + \frac{7}{20} = 3 \frac{10}{20} = 3.5[/tex]
So, we have:
A. - something
B. around 10
C. a bit less than 3.5
D. exactly 3.5
So, from least value to the greatest value, the order would be:
A, C, D, B
