30% of a group of 80 children wear black socks. How many wear black socks?
How do I work this out?
So you want 30% of 80.
30% is 30/100 which is 0.3
So you multiply 0.3 by 80
which is 24.
So 24 children wear black socks because 30% of 80 is 24.
convert a percentage to a decimal, and divide the result by 100.
30% becomes .30 or .3
Multiple the decimal by the number of children: .3 * 80 = 24.0
