Nyla writes 1/4 of a page and 1/8 of a minute. how much time does it take her to write a full page ? answer

For this case we can make the following rule of three:
 1/4 > 1/8
 1 > x
 From here, we clear the value of x.
 We have then:
 x = (1 / (1/4)) * (1/8)
 Rewriting:
 x = 4 * (1/8)
 x = 4/8
 x = 1/2 minutes
 
 it takes her 1/2 minutes to write a full page
