Well you can start by dividing 20 by 2 because that would give you the half that you finished in class 24 divided by 2 =12 if you finish four more you wound have 12-4=8 you have 8 problems left and now you have to find the fraction so start with 8/24 and then simplify your answers would be 1/3
Answer:
[tex]\frac{8}{24} =\frac{1}{3}[/tex]
Step-by-step explanation:
In order to solve this, you just have to add up the fractions and calculate how much is that:
[tex]\frac{24}{24}- (24(\frac{1}{2} )+\frac{4}{24} )\\[/tex]
Now you just have to add up and then withdraw from the total:
[tex]\frac{24}{24}- (24(\frac{1}{2} )+\frac{4}{24} )\\\frac{24}{24}- \frac{12+4}{24} \\\frac{24}{24}- \frac{16}{24} =\frac{8}{24}[/tex]
SO now we know that he has 8/24 problems to do, if we reduce that we have that he still has to do 1/3 of the problems.
