Answer:

Because you have to give the simplest ratio of equation. Equation I can be simplified by dividing all the coefficients by 2 to make it into equation II.

*Every equation has to be in the simplest form of coefficients.

Ratio of Equation I :

2 : 4 : 2 : 4

Ratio of Equation II :

1 : 2 : 1 : 2
