Answer:
I. Boys, B = 210 learners.
II. Girls, G = 240 learners.
Explanation:
Let the number of boys be B.
Let the number of girls be G.
Given the following data;
Total number of learners = 450 learners.
Ratio of B to G = 7:8
Ratio = 7 + 8 = 15
To find the value of B;
[tex] B = \frac {7}{15} * 450 [/tex]
[tex] B = \frac {3150}{15} [/tex]
Boys, B = 210 learners.
To find the value of G;
[tex] G = \frac {8}{15} * 450 [/tex]
[tex] G = \frac {3600}{15} [/tex]
Girls, G = 240 learners.
