You can put this solution on YOUR website!
1 year = 365 days (assuming we're not talking about a leapyear)
1 day = 24 hours
1 hour = 60 minutes
Use those equalities above to convert from 1 year to minutes.
*\left(\frac{365 \text{ days}}{1 \text{ year}}\right)*\left(\frac{24 \text{ hours}}{1 \text{ day}}\right)*\left(\frac{60 \text{ minutes}}{1 \text{ hour}}\right))
\text{ minutes})
There are about 525,600 minutes in 1 year
Since there are about 2.8 million births in 1 year, we can form the ratio
2.8 million births : 525,600 minutes
Which is the same as writing out
2,800,000 births : 525,600 minutes
Now divide both parts of that ratio by 525,600 to turn the "525,600 minutes" into "1 minute"
So we get
2,800,000 births : 525,600 minutes
(2,800,000)/(525,600) births : (525,600)/(525,600) minutes
5.32724505327246 births : 1 minutes
We have about 5.32724505327246 births every 1 minute
Rounded to two decimal places to simplify things a bit, we have about 5.33 births per minute.
Answer: Approximately 5.33 births per minute
