Answer:
To find the number of boys and girls in grade 8, we first need to determine the total number of parts in the ratio 4:5, which represents the total number of learners.
Since the ratio of boys to girls is 4:5, the total number of parts is 4 + 5 = 9.
Now, we can find the number of learners represented by each part by dividing the total number of learners (36) by the total number of parts (9):
Total learners represented by each part = Total learners / Total parts
Total learners represented by each part = 36 / 9 = 4
Now, we can find the number of boys and girls by multiplying the number of parts for each gender by the number of learners represented by each part:
Number of boys = 4 parts * 4 learners/part = 16 boys
Number of girls = 5 parts * 4 learners/part = 20 girls
So, there are 16 boys and 20 girls in grade 8.
