Answer 2

A ratio is a mathematical expression written in the form of a:b, where a and b are any integers. It expresses a fraction.

Let the number of student in a class $200$

$55$ % of girls

So $110$ girls

Boys $=90$

On monday $80$% of boys, student are present

i.e., $\frac{80\times 90}{100} =72$

$70$% student were present that day of the total

i.e. $\frac{70\times 200}{100}= 140$

girls present on that day is

$=140-72$

$=68$

$=\frac{68\times 100}{110}$

$=61.8$%
