Answer:
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%
