OpenStudy (mathstudent55):

First, any negative number is less than any positive number. That takes care of A.

OpenStudy (gorv):

what do u think??

OpenStudy (gorv):

5.7>5.6 is it true??

OpenStudy (mathstudent55):

B. is a comparison of regular, positive numbers. What is more $5.70 or $5.63?

OpenStudy (mathstudent55):

For C. and D. , you are comparing two negative numbers. Negative numbers work the opposite of positive numbers. The larger the number looks (when you take away the negative sign), the smaller it is.

OpenStudy (mathstudent55):

Now read the above explanations, and tell me what you think the answer is.

OpenStudy (vianne):

A. –13.9 > 4.63 B. 5.7 < 5.63 C. –4.28 > –3.56 D. –4.37 < –1.63 B is the correct answer. Negative numbers are smaller than positive numbers. Also 5.70 is greater than 5.63 due to the fact that 60 is smaller than 70. ;)

sorry i was helping another kid okay i think it's D but it could be B right I don't know :(

OpenStudy (mathstudent55):

B is not true. In B, 5.7 < 5.63 Think of money. 5.7 is $5.70. 5.63 is $5.63 What is more 5 dollars and 70 cents or 5 dollars and 63 cents?

OpenStudy (mathstudent55):

The correct answer is D.
