Answer 2

${\huge{\bold{\purple{\bigstar{\boxed{\boxed{Question}}}}}}}$

• There are 57 students in the class. 2/3of the students are girls. How many boys are there in the class?

${\huge{\bold{\purple{\bigstar{\boxed{\boxed{solution}}}}}}}$

$\sf{\bold{\blue{\boxed{\boxed{Given}}}}}$

• Total students = 57
• fraction of girls = 2/3

$\sf{\bold{\blue{\boxed{\boxed{To\:find}}}}}$

• No. of boys

$\sf{\bold{\blue{\boxed{\boxed{solution}}}}}$

$\sf\implies{no. \: of \: girls = \dfrac{2}{3}\times 57}$

$\sf\implies{no. \: of \: girls = \dfrac{2}{\cancel 3}\times \cancel 57}$

$\sf\implies{no. \: of \: girls = {2}\times 19}$

$\sf\implies{no. \: of \: girls = 38 }$

$\sf\implies{total\:students = girls + boys}$

$\sf\implies{57 = 38 + boys }$

$\sf\implies{boys = 57 - 38}$

$\sf\implies{boys = \: 19}$

$\sf{\bold{\green{\boxed{\boxed{No.\: of\:boys = \: 19}}}}}$
