(will give brainly) orde the values on the cards below in ascending order
VMariaS [17]

Answer:

Step-by-step explanation:

Set 1

first of all we have to look at the negative numbers:

-99% = -0,99

-√80 = is almost 9

so :

-9,(9) ; -√80 ; -99%

then the positive numbers:

19% = 0,19

√9 = 3

1/9 = 0,11...

so

1/9 ; 19% ; √9

final answer:

-9,(9) ; -√80 ; -99% ; 1/9 ; 19%, √9

Set 2

descending order = from greatest to least

In this case we have to look at first at positive numbers

2/3 = 0,6

√23 = 4,...

20/3 = 6,...

23% = 0,23

so

20/3 ; √23 ; 2/3 ; 23%

negative numbers

-√34 = -5,...

so :

-4,(3) ; -√34

final answer:

20/3 ; √23 ; 2/3 ; 23% ; -4,(3) ; -√34
