Nezavi [6.7K]
1. You could write it as a rate.
5 movies         =  75 movies
25 TV sitcoms =  x sitcoms

2. Cross multiply:
5x = 1875

3. Divide
x = 375 TV sitcoms

you could do the same thing for the second question
5 movies    = x
25 sitcoms = 50 sitcoms

cross multiply:
25x = 250

divide:
x = 10
