order from least to greatest:
2.7, 2 1/7, 3.13, 1 9/10

Change the two fractions to decimals.
2 1/7 = 2.14
1 9/10 = 1.9
I'll be glad to check your answer. 
3.13,2.14 2.7,1.9 ??????????

No.
First, you're supposed to arrange them from least to greatest.
Think of money. Which is more? $3.13 or $1.90?
Which is more? $2.14 or $2.70? 
$3.13 and $2.70

so it would be
3.13,2.70,2.14,1.9 ????????????? 
That isn't least to greatest!
