first we have to figure out how many slices each of them ate
brian ate 1/3 of 12 which is 4
mother ate 1/6 of 12 which is 2
together they both ate 6
12-6 is 6
there were 6 slices left
brian ate 1/3 of 12 which is 4

Only 6 slices were left of the Pizza. Put 12 slices into a ratio 12/12. 1/3 x 4 is 4/12 so thats 4 slices brian Ate and 1/6 x 2 is 2/12 so thats 2 slices his mother ate. 2+4=6 Slices of pizza. 12-6 = 6 remaining pieces of pizza.
