A.y/(x + y)
B.x/xy
C.x/(x + y)
D.y/xy

Answer 1

x/(x+y) is the answer

Answer 2

The correct answer is option (C) x/(x+y)

GIVEN

Number of girls = x

Number of boys = y

TO FIND

Part of the class is composed of girls.

SOLUTION

We can simply solve the above problem as follows;

It is given,

Number of girls = x

Number of boys = y

The total strength of the class = Number of boys + Number of girls.

= x + y

To find out the part that is composed of girls we will write the strength of the class in the denominator and number of girl students in the numerator

Therefore,

The part representing number of girls in the class is given by,

$\frac{x}{x + y}$

Hence, The correct answer is option (C)/
