In a group of 28, 16 are boys 12 are girls. what fractional part of the group are boys?

16/28 = 4/7

To determine the fractional part of the group that are boys, you need to divide the number of boys by the total number of people in the group.

In this case, there are 16 boys and 12 girls, so the total number of people in the group is 16 + 12 = 28.

So, to calculate the fraction of boys in the group, you divide the number of boys (16) by the total number of people in the group (28):

Fraction of boys = Number of boys / Total number of people
= 16 / 28

To simplify the fraction, you can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 16 and 28 is 4.

Fraction of boys = 16 / 28
= (16 ÷ 4) / (28 ÷ 4)
= 4 / 7

Therefore, the fractional part of the group that are boys is 4/7.
