<h3>Ratio and proportions</h3>
Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:
0.2 of a book = 1.5 hours
In order to determine the time taken to read 0.75 part of the book, we will have:
0.75 of a book = x
Take the ratios
0.2/0.75 = 1.5/x
0.2x = 1.125
x = 1.125/0.2
x = 5.625
Hence it will take her 5 5/8 hours to read 3/4 of the book
