A class has 6 boys and 15 girls. What is the ratio of boys to girls?
Answer (3)
t h e r a t i o i s : b oys t o g i r l s = 6 : 15 = 2 : 5
we know that
Ratio is the quantitative relation between two numbers
so
Let
x-------> number of boys in the class
y-------> number of girls in the class
r a t i o = y x
in this problem we have
x = 6 b oys y = 15 g i r l s
Find the ratio
substitute the values in the formula
r a t i o = 15 6
Divide by 3 both numerator and denominator
r a t i o = 5 2
therefore
the answer is
the ratio of boys to girls is 5 2
The ratio of boys to girls in the class is 2:5. This means for every 2 boys, there are 5 girls. This ratio can be simplified from the original count of 6 boys and 15 girls.
