The ratio of boys to girls at a school is 5:4. If there are 255 boys at the school then how many students are there at the school?
Answer: students.
There are 1400 students in a school.The number of girls is 3/4 the number of boys. How many students are in other levels if 1/6 of the girls and 1/5 of the boys are in Primary One
g = 3/4 b
g+b=1400
7/4 b = 1400
b = 800
g = 600
1st grade boys: 1/5 * 800 = 160
1st grade girls: 1/6 * 600 = 100
total 1st grade: 260
others: 1140
