Answer:

50 boys and 75 girls

Step-by-step explanation:

Given

[tex]Boys: Girls = 2 : 3[/tex]

[tex]Total = 125[/tex]

Determine the number of boys and girls

The number of boys is:

[tex]Boys = \frac{Boys\ Ratio}{Total\ Ratio} * Total[/tex]

[tex]Boys = \frac{2}{2 + 3} * 125[/tex]

[tex]Boys = \frac{2}{5} * 125[/tex]

[tex]Boys = 0.4 * 125[/tex]
