Hey there!
Ratios can also be expressed as fractions. The first number will be your numerator while the second number will be your denominator.
![7:3 = \frac{7}{3} =2 \frac{1}{3}](https://tex.z-dn.net/?f=7%3A3%20%3D%20%20%5Cfrac%7B7%7D%7B3%7D%20%3D2%20%5Cfrac%7B1%7D%7B3%7D%20)
![8:4 = \frac{8}{4} = 2](https://tex.z-dn.net/?f=8%3A4%20%3D%20%20%5Cfrac%7B8%7D%7B4%7D%20%3D%202)
![9:5 = \frac{9}{5} = 1 \frac{4}{5}](https://tex.z-dn.net/?f=9%3A5%20%3D%20%20%5Cfrac%7B9%7D%7B5%7D%20%3D%201%20%5Cfrac%7B4%7D%7B5%7D%20)
![2:7 = \frac{2}{7}](https://tex.z-dn.net/?f=2%3A7%20%3D%20%5Cfrac%7B2%7D%7B7%7D%20)
You could then divide these fractions out by dividing the numerator by the denominator to see which is the largest, but we can already tell that 2 1/3, or 7:3, will be the largest, since none of the other fractions are that large.
Hope this helped you out! :-)
