Question

Yasmin want to serve 150 ml juice to each of 15 guest how much 500 ml cartoon of juice should she buy how much juice will she be left with after serving her guest

Answer 1

According to question:-
no. of cartoons= (150.15)/500
                        = 2250/500
                        =4.5

So, Yasmin should buy 5 cartoon and she will be left with 1/2 cartoon.

Answer 2

First calculate the total amount of juice needed
Amount of juice needed= juice for each person* amount of people
Therefore amount=150*15=2250ml of juice
Now divide the total amount by the 500 ml carton.
2250/500=4 cartons+250 ml.
Therefore 5 cartons should be bought.
500*5=2500
And 2500-2250= 250.
So, 250 ml of juice will remain after she serves her guests.
