Can someone me? i am trying to figure out my little sisters homework and i can't do it

Answer is A. 3 1/4 is to the left of 7/2 and 7/2 is to the left of 3.75.
With a horizontal line, they are talking about the integers from positive to negative. as you go left the numbers decrease and as you go right the numbers increase
First change 3 1/4 and 7/2 into decimals
3 1/4= 3.25
7/2= 3 1/2= 3.5

Here are your decimals from least to greatest.
3.25, 3.5, 3.75
So 3.25 (3 1/4) is to the left of 3.5 (7/2) and it is to the left of 3.75
