Answer 2

Answer:

Required fraction is $\frac{5}{12}$

Step-by-step explanation:

Here given,

In a school $\frac{7}{12}$of the students are boys .

And number of students are 1176.

This is a problem of Algebra.

Total number of boys$= \frac{7}{12}$

of total students

$= \frac{7}{12} \times 1176 \\ = 7 \times 98 = 686$

Hence total number of boys in the school are 686.

And number of girls = Total number of students - Total number of boys =1176-686=490

So, number of girls are 490.

By Unitary method,

Now 1176 means here total 1 part and 1 means here $\frac{1}{1176}$part

490 means here $\frac{1}{1176} \times 490 = \frac{245}{588} = \frac{35}{84} = \frac{5}{12}$

Required fraction is $\frac{5}{12}$
