Step-by-step explanation:

Given that:

The total enrollment in a school is 1800 of these, 850 are boys and the remaining are girls.

To Find:

The ratio of,

1. Number of boys to the total enrollment of the school.
2. Number of girls to the total enrollment of the school.
3. Number of girls to the number of boys in the school.

Finding the ratio of:

Number of boys to the total enrollment of the school.

Boys : Total enrollment = 850 : 1800

Dividing by 50.

Boys : Total enrollment = 850/50 : 1800/50

Boys : Total enrollment = 17 : 36

Number of girls to the total enrollment of the school.

Girls : Total enrollment = (Total enrollment - Boys) : Total enrollment

Girls : Total enrollment = (36 - 17) : 36

Girls : Total enrollment = 19 : 36

Number of girls to the number of boys in the school.

Girls : Boys = 19 : 17
