After converting to common denominator:
8/18, 7/18, 6/18, 5/18
so the next fraction is 4/18, but if you have to simplify it’s 2/9 
        
             
        
        
        
Hey!

Solution:
The ratio is FEMALES to MALES.
So its 18/16, 18:16, or 18 to 16.
~Now we need to simplify.
18:16 → 18/2:16/2 → 9:8
*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.

Answer:
5.2 in
Step-by-step explanation:
An equilateral triangle is a triangle with 3 equal sides 
Divide the equilateral triangle into two congruent triangles and use Pythagoras theorem to find the height
The Pythagoras theorem : a² + b² = c²
where a =  height
b = base = 6 in / 2 = 3 in  
c =  hypotenuse = 6 in 
6² = 3² + h² 
h = 36 - 9 = 27
√27 = 5.196 inch
to the nearest tenth = 5.2 in
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
