Approximately 32,400 citizens of the country died in 2015. Express the toll in deaths per day
Zigmanuir [339]

There is 90 deaths per day.

First it tells us 32,400 people died in 2015, which also mean that many people died that year.

We have to find the number of people died each month first.

32,400÷12 because 12 is the total number of months in a year.

2700 people died in a month, not we need to find how many people died each day so we divided it by 30 and we get

90 deaths per day.
