this makes no sense, so imma guess for u.
C
D because d is always right hahahahaha
128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3
Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3
I believe it is 24 batches:
because there are 8/8 in one hour, so you multiply that by three. which would give you 24!
