Question

Can Someone tell me how to do this?

Answer 1

Number 7 is C because all of them are less than 1/2 or 0.50

Answer 2

3/9 is equal to 1/3 when simplified so no not all numbers are greater than 1/3
.4 Is greater then .39 so no not all numbers are less than .39
30/100 is .3 so no not all numbers are greater than . 3
3/9 is .3333 and 30/100 is .3 so yes all numbers are less than 1/2 or .5
C is the answer
