Answer:
A: 85%, 2 , 3.24,
, 3.24,  
B: covert numbers into percent
Step-by-step explanation:
<u>Part A</u>
We have:
 , 2
, 2 , 85%, 3.24 --> let's convert them into percentages like the 85, to determine which one is greatest/least:
, 85%, 3.24 --> let's convert them into percentages like the 85, to determine which one is greatest/least:
85% --> 85% (already a percent)
   --> to convert into percent: (19÷4) x 100 = 475%
 --> to convert into percent: (19÷4) x 100 = 475%
2 --> convert first into improper fraction then into percent: (11/5) x 100 = 220%
 --> convert first into improper fraction then into percent: (11/5) x 100 = 220%
3.24 --> multiply by 100: 3.24 x 100 = 324%
From least to greatest: 85%, 220%, 324%, 475%
= 85%, 2 , 3.24,
, 3.24,  
Part B:
In part A, to determine the numbers from least to greatest, we rewrote the numbers all into percentage form by first converting into decimal form and then multiplying by 100.
