Essentially yes

Hi,

I am trying to understand what this question asks, why we do not have to add deaths of non elderly people from division ?
(Ex, 13000 for houston is the number of only elderly people and is not including the number of deaths of none elderly people.)

The pie chart tells us that 12% of the 3532 pneumonia/influenza deaths occurred in Houston.
That works out to about 424 deaths from pneumonia or influenza in Houston.
These 424 consisted of both elderly and non-elderly people.

The question asks to assume that 80 percent of all deaths due to pneumonia or influenza occur among the ELDERLY.
80% of 424 = 339.
So, 339 ELDERLY people in Houston died from pneumonia or influenza in Houston.
In the same year, about 13,000 ELDERLY people in Houston died

So, the ratio = 339/13,000

Hi GreenLightTestPrep,

Thank you for replying, I may be miss understanding this question, but why we can divide by 13,000 ?
The question was not clear to me whether we should divide by 13,000 or we should divide by 25,000 (13,000 for elderly and 12,000 for less than 1 year).

I could not understand which sentence / word specifies the scope of denominator.
(I think I have difficult time to find out proportion to what.)

Thank you for your support.

Best,
Gocha

Think of proportion are ratio

We want: In which city was the least proportion of all deaths among the elderly attributed to pneumonia or influenza?
In other words we want the smallest value of (# of elderly who died of pneumonia/influenza)/(total # of elderly deaths)
