Question

Louis has 45 pencils and 75 pens to divide into gift bags at the fair he does not want to mix the pens and pencils he wants to place an equal amount in each bag what is the greatest place in each bag

Answer 1

Factor both these numbers:

• 45=3·3·5;
• 75=3·5·5.

The greatest common factor (write all common factors and multiply them) is 3·5=15. Then:

• 45=15·3;
• 75=15·5.

Conclusion: Louis can form at most 15 bags, each of them will contain 3 pencils and 5 pens.

Answer 2

You can out 15 pencils in each bag because.
15+15+15=45
15+15+15+15+15=75
