OpenStudy (anonymous):

thanks I thought it was c too lol

OpenStudy (mathstudent55):

No. C is false.

OpenStudy (mathstudent55):

7.1 could be thought of 7.10 Think of $7.10 (7 dollars and 10 cents) Is 7 dollars and 10 cents more than 7 dollars and 24 cents?

OpenStudy (anonymous):

so it would be b and thanks for telling me i thought it was c

OpenStudy (mathstudent55):

B is true, but it's not the only one.

OpenStudy (mathstudent55):

When you compare negative numbers, pretend they are positive. Then the one that is larger is really the smaller one.

OpenStudy (mathstudent55):

Let's use A as an example. -8.93 > -8.4

OpenStudy (mathstudent55):

Remove the negative signs and get: 8.93 > 8.4 For positive numbers this is true, so for negative numbers it is false.

OpenStudy (mathstudent55):

A is false. B is true. C is false. What about D?

OpenStudy (mathstudent55):

Is 3.2 > 3.6 true or false? Whatever it is, -3.2 > -3.6 is the opposite.

OpenStudy (anonymous):

so b and d

OpenStudy (mathstudent55):

Yes
