Lola measures three buttons for a shirt she is making. one button is 1/8inch, one is 3/8inch, and one is 1/4inch. which button is smallest? which is largest

Well, you can turn these into percents to get a different view if the fraction thing is messing you up. Do this by dividing the top by the bottom and multiplying bu 100. 

1/8 = 0.125           0.125 x 100 = 12.5%
3/8 = 0.375           0.375 x 100 = 37.5%
1/4 = 0.25             0.25 x 100 = 25%

1/8 is the smallest and 3/8 is the largest

Another way to do this would be to multiply 1/4 so all three numbers have equal denominatior. 
1/4 x 2/2 = 2/8 

comparing, 2/8 3/8 and 1/8, you can see that 1/8 is the least and 3/8 is the most
