A school has 850 learners . The ratio of girls to boy is 6 : 4 . How many learners are girls?
Answer in numbers
The ratio of girls to boys is 6:4, which means the total ratio is 6+4 = 10.
So the fraction of girls in the school is 6/10.
To find out how many learners are girls, we first need to calculate 6/10 of 850.
6/10 * 850 = 510
Therefore, there are 510 girls in the school.
