All the children of a class were asked to choose between the cartoon shows 'Shin Chan' and 'Tom and Jerry'.The ratio of children who selected the cartoon 'Shin Chan' to those who selected the cartoon 'Tom and Jerry', was 3:1.

If there are 45 as the 3 ratio, you just divide the 45 by 3 and it gives you the 1 ratio. 45/3= 15, so 15 children picked atom and Jerry. 45+15= 60. There are 60 students in class :)
