40m increased by 30% is 52m

To increase 40 by 30% you need to add "30% of 40m" to the original 40m.

To calculate 30% 0f 40m we know "Percent" or "%" means "out of 100" or "per 100", Therefore 30% can be written as #30/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Putting this together we can write:

#30/100 * 40m = (1200m)/100 = 12m#

Adding the 12m to the original 40m gives:

#40m + 12m = 52m#
