Answer 2

@ranga please help!

Answer 3

To add or subtract fractions you need to have a common denominator.

Multiply the top and bottom of the first fraction by 3.
Multiply the top and bottom of the second fraction by y.
Subtract.

Answer 4

12y/3y^2 - 5y^2/3y^2?

Answer 5

Multiply the top and bottom of the first fraction by 3.
4/y^2 * 3 / 3 = 12 / (3y^2)
Multiply the top and bottom of the second fraction by y.
5/(3y) * y / y = 5y / (3y^2)
The denominators are the same. So you can subtract the numerator:
(12 - 5y) / (3y^2)
