Answer:
At least 3 bags will be required to pack the fruit in equal amount.
Step-by-step explanation:
Given:
Number of apples she buys =15
Number of oranges she buys = 18
Number of mangoes she buys = 21
we need to find the least possible number of bags used.
Solution:
To find the least possible number of bags required we will find the prime common factor.
Multiples of 15 = [tex]3\times 5[/tex]
Multiples of 18 = [tex]3\times 3\times 2[/tex]
Multiples of 21 = [tex]3\times 7[/tex]
so we can say that;
Highest common prime factor in all three numbers is 3.
Hence At least 3 bags will be required to pack the fruit in equal amount.
