4/9 * 1/2 = 4/18 = 2/9

So, the boys with brown eyes are 2/9 of all the students that attend the math club

from the whole group half the club are boys.
fraction of boys from the whole class = 1/2
from this fraction, 4/9th of the boys have brown eyes
therefore fraction of boys who have brown eyes
= 4/9 of 1/2
the 'of' function is used to multiply

(4)/(9) * (1)/(2)
when multiplying fractions numerators are multiplied by numerators and denominators multiplied by denominators

(4*1)/(9*2) = (4)/(18)
4/18 can be simplified by dividing the whole number by a common number
4/18 divided by 2 = 2/9
the answer is 2/9
2/9 of the club are boys with brown eyes
