The total number of children is the sum of the number of boys and girls. So we have:
Total number of children = Number of boys + Number of girls
Total number of children = 4 boys + 5 girls
Total number of children = 9 children
The ratio of the number of boys to the total number of children is therefore:
Number of boys : Total number of children
4 : 9
This ratio can be expressed as a fraction representing the boys' proportion of the total group:
Fraction representing the boys' proportion = Number of boys / Total number of children
Fraction representing the boys' proportion = 4 / 9
So the ratio of the number of boys to the total number of children is 4:9.
