Question

in a class 3/5 of the student are girls and rest are boys if 2/9 the girls and 4/9 of the boys are absent what part of the total number of student are present ​

Answer 1

Answer:

14/45

Step by step explanation:

If 3/5 of the students are girls then

1-(3/5) = 2/5 of the students are boys.

If 2/9 of the girls are absent

it means

(2/9)* (3/5) of the students are absent.

which is equal to

2/15

If 4/9 of the boys are absent

it means

(4/9)*(2/5) of the students are absent

which is equal to

8/45

So total number of students absent is equal to

(2/15)+(8/45)

which is equal to

14/45

14/45 of the students are absent
