Question

Medicine is packed in boxes, each weighing $$4$$ kg $$500$$g. How many such boxes can be loaded in a van which cannot carry beyond $$800$$ kg?

Answer 1

$$1$$ kg $$=1000$$g
$$4$$ kg $$500$$ g$$=4500$$g
$$800$$ kg $$=8\times 1000=800000$$g
Number of boxes that can be loaded in the van $$=800000\div 4500$$
$$177$$
_________
