Tpy6a [65]

Answer:

A. 27

Step-by-step explanation:

There are 40 students and 90% of them take exams

(40 students) * (0.9) = 36 students took exams

Of those 36 students, 75% (or 3/4) of them passed. Assuming passing exams means graduating:

(36 students) * (0.75 ) = 27 students graduated

There are 180 students participating in after school activities. Of those students 40% are boys . How many girls are participati

Nezavi [6.7K]

i dont want to assume all the other people participating in after school activities are girls but if they are, the answer is 108.

180 = 100%

x = 40%

the information above shows that 60% are girls

60% of 180 = 108 or 0.60 x 180 = 108

the answer is 108

hope this is helpful!
