You just have to draw a number line where you put the numbers in order. I brought all fractions to one common denominator which is 20 and plotted them on the number line.
First, you look for a common denominator, which is 20. Since 2 is a multiple of 20, you need to multiply it by 10. Since you multiplied it by 10, you also need to multiply the numerator by 10, giving you 10/20. Remember, you do not multiply the whole number in front of the fraction. You also do the same thing with the first one. Since you need to multiply the denominator by 4, you also need to multiply the numerator by 4, making it 16/20. Now that you have all of the denominator the same, you can now figure out the order from least to greatest by looking only at the numerator. I trust you that you know which ones are greater and which one are lesser.
I hope i helped you. Reply back if you don't understand anything.
