Astudent 1/3 of clay and a other student has 5/8 of clay what do you do if you have to divide it

So basically this qestion is asking you to add 1/3 and 5/8 together and divide the result by 2 so first get the denomenator (bottom number ) the same
1/3=8/24
5/8=15/24
8/24+15/24=23/24
divide this by 2 and get
23/48 of clay
