anyanavicka [17]

A.) The clerk has - 16 oranges 20 apples 24 pears


he needs to put all three fruits into baskets without any leftover fruits


each basket should have equal amounts of each fruit


so to find the largest number of baskets he can make we have to find the highest common factor for 16,20 and 24


so lets find the factors for each of these


16 - 1,2,4,8,16


20 - 1,2,4,5,10,20


24 - 1,2,3,4,6,8,12,24


from the given factors the common factors for all three are 1,2 and 4


from these the highest factor is 4


therefore the largest number of baskets he can make are 4


in each basket there will be


4 oranges 5 apples 8 pears



answer is 4 baskets
