Answer: 1) 1/2 students like to go to action movies,

2) 2/5 students like to go to action and comedies.

Step-by-step explanation:

Let the total number of students are x,

Thus, the number of students who like to go movies = 3/4 of total students = \frac{3x}{4}

The number of students who like to go action movies = 2/3 of students who like to go movies = 2/3 of 3x/4 = \frac{6x}{12} = x/2

Hence, the total fraction of students who like to go action movies = Number of students who like to go action movies / Total students

= \frac{x/2}{x}

= 1/2

Now, the number of student who like to go comedy movie = 4/5 of the students who like to go action movies

= 4/5 of x/2

= \frac{4x}{10}

= \frac{2x}{5}

Hence, the fraction of students who like to go comedy movies

=  Total students who like comedies/ Total students

= \frac{2x/5}{x}

= 2/5

Hi, thank you for posting your question here at Brainly.

The process of solving this problem is as follows:

Students who like action movies: 3/4*2/3 = 1/2 of the fifth grade class students
Students who like comedies: 1/2*4/5 = 2/5 of the fifth grade class students

The sum of two numbers is 148. The larger number is two less than three times the smaller. What are the two numbers?
Lyrx [107]
Let
x--------->  the larger number
y---------> the smaller number

we know that
x+y=148------> equation 1
x=3y-2------> equation 2

substitute 2 in 1
[3y-2]+y=148--------> 4y=150---------> y=150/4------> y=37.5
x=3y-2----> x=3*37.5-2-----> x=110.5

the answer is
the larger number is 110.5
the smaller number is 37.5
