In a class, 3/5 of the kids are girls. 2/5 of the boys play tennis. None of the girls play tennis. What fraction of the class play tennis?

2/5

Step-by-step explanation:

No of girls in the class=3/5

No of boys in the class=2/5

3/5+2/5=1

No of the class that play tennis

1-3/5

=2/5

2/5

Step-by-step explanation:

3/5 of the class are girls

While 2/5 of the boys play tennis.

If none of the girls play tennis, then we have exactly 2/5 of only the boys who play tennis as fraction of the class that play tennis.

But if a fraction of the girls play tennis, that fraction would have been added to the fraction of the boys who play tennis. But since, There are no girls who play tennis, none would be added, therefore the fraction remains 2/5 of the class

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

what i would say the best answer is a. 40.5
