Thank you for the opportunity to help you with your question!

The ratio of blue pencils to red is .15 : .35

The whole set of pencils will be .15 + .35=0.5

To find the number of blue pencils, we solve the problem as indicated below:

=.15/.5 * 40=0.3 * 40=12 blue pencils.

Please let me know if you need any clarification. I'm always happy to answer your questions.
