You can put this solution on YOUR website! if the average of the ages of 25 girls is 14 years and 2 months, then the sum of their ages is 25 * (14 years and 2 months) which is equal to 25 * 14 years plus 25 * 2 months which is equal to 350 years plus 50 months which is equal to 354 years and 2 months.
you have the sum is 354 years and 2 months.
this is equivalent to 354 and 1/6 years.
in decimal form that's 354.1666666666........ years.
divide that by 25 and you get an average of 14.16666666...... years per girl.
that's equivalent to 14 years and 2 months of age per girls on the average.
