Isn't the last part 1/4 because that is AC? why is it 3/4

[sonic egret]

it should be 1/4 yes

[honest spoke]

yeah but ur getting confused

AC = 1/4 OC

but OA is 4a

and OA is 3/4 OC

so naturally, 1/4 would then just be this divided by 3 so 4/3a

basically OA:AC is 3:1

OA is 4a, so AC is gonna be that divided by 3

[stoic stirrup]
