Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558
so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls
Answer:
n = 98
Step-by-step explanation:
8/11 x (n - 10) = 64
multiply both sides of the equation by 11/8
11/8 x 8/11 x (n-10) = 11/8 x 64
reduce the numbers with greatest common divisor 11
1/8 x 8 (n-10) = 11/8 x 64
n - 10 = 11 x 8
multiply the numbers
n - 10 = 88
so then you add the numbers
n = 88 + 10
n= 98
