Answer:
5 packs of eggs
3 packs of spoons
Explanation:
Eggs are sold in packs of 6
Spoons are sold in packs of 10
The teachers want to have 1 egg for every spoon
Find the Lowest common multiple of 6 and 10
6 = 12, 18, 24, 30, 36, 42, 48, 54, 60
10 = 20, 30, 40, 50, 60
The lowest common multiple of 6 and 10 is 30
If the teachers want to buy exactly 30 spoons and have no leftovers
Eggs are sold in packs of 6
Number of packs needed = 30 /6
= 5 packs
Spoons are sold in packs of 10
Number of packs needed = 30/10
= 3 packs
The teacher will buy 5 packs of eggs and 3 packs of spoons to have exactly 30 spoons and have no leftovers
