Answer:
The boy has 28 blue pencils
Step-by-step explanation:
Given
Total pencils = 40
The ratio of red to blue= 0.15:0.35
We have to find the number of blue pencils
For that we need the sum of ratio = 0.15+0.35 = 0.5
So, the number of blue pencils = (ratio of blue/sum of ratio) * total pencils
=0.35/0.5 * 40
=0.7*40
=28 pencils
Therefore, the boy has 28 blue pencils ..
