the answer is 1.44444444 I got it by doing : 26 divided by 18 = 1.44444444
Ok, so I'm pretty sure you get it by just dividing 168 by 182 to get 0.923 etc. Then if you multiply it by 100 then you get your grade. Which is about a <em>92.3%</em>. Hope this helps.
There are 23 students in Ms. Jane’s class. Because you do 138/6 and you get 23.
