perl · Answer

it says what percent of 50 year olds belong to group A. so we are only looking in the 50 year old column. of these 50 year olds, what percentage is in group A

anonymous · Answer

you literally just rephrased what it says ..

anonymous · Answer

Percentage come to describe apart of a whole.
If I get the question right, they want to know how many out of all the 50 years old men people are belong to group A.
We know how many 50 years old people are there in total and we know how many of them are in group A, so now take the ratio and multiply by 100 to get the percentage:
$$\frac{	ext{50_years_old_in_group_A}}{	ext{50_years_old_in_total}}\cdot 100 = 	ext{percentage}$$

anonymous · Answer

I get 1.75

perl · Answer

what is the total of 50 year olds ?

anonymous · Answer

56

perl · Answer

what is the total of 50 year olds who are in group A

anonymous · Answer

32

perl · Answer

ok, now plug in  
50_ year_old_in_group A /  total_50_year_olds 
=  32/ 56

perl · Answer

the last step is to multiply by 100

anonymous · Answer

You got 1.75 because you accidentally did the 56/32 instead of 32/56. you also didn't multiply by 100 afterwards =]
