How do we solve question 21

plz : -)

Order from least to greatest:
19/6, 3 5/14, 83/21

So idk if you actually want the answer or not (you said "how do we solve this"), but here's how you get it:

First thing you'll want to do is make all three numbers improper fractions. You will have 19/6, 47/14, and 83/21. 

Next, find the least common denominator. For this problem, it would be 42. You have to figure out what you multiplied the denominator by to get to 42, and multiply the numerator by the same number. For example, you multiplied 6 by 7, so multiply 19 by 7 as well. 

You should end up with 133/42, 141/42, 166/42. 

Then, organize those from least to greatest and put them back in their original form:)
