You can put this solution on YOUR website!
total number of students is 60.

let x = the number of students in fred's class.

then 1.4 * x = the number of students in lee's class.

your equation is:

x + 1.4 * x = 60

combine like terms to get 2.4 * x = 60

solve for x to get x = 60 / 2.4 = 25

that's the number of students in fred's class.

lee's class has 60 - 25 = 35.

the ratio of students in lee's class to students in fred's class is 35/25.

25/25 decimal equivalent is 1.4.

that's the ratio of students in lee's class to students in fred's class.

solution looks good.

solution is that there are 35 students in lee's claws.
