Last year, 73,249 people died from diabetes mellitus in the United States. The total number of deaths from all causes was 2,443,387, and the total population was 288,356,713. Calculate the proportionate mortality ratio for diabetes mellitus.

2.998% or 3 out of every 100 deaths was caused by diabetes mellitus

Explanation:

The formula to calculate proportional mortality ratio is:

Deaths caused by a particular cause divided by Deaths from all causes× 100.

Deaths caused by diabetes mellitus = 73,249

Total deaths by all causes = 2,443,387

So we have: 73,249/2,443,387 = 0.029978, multiply this by 100

0.029978 x 100 = 2.9978% approximating to 3 decimal place will give you 2.998%
