2x +Qy = 8

-2x +6y = -8
2x +Qy = 8

Answer with explanation:

Consider a Rectangular room, in which four people are residing and another congruent room,in which six people are dwelling.

If Area Occupied by two rooms are same

Then, Area occupied by each person in first room,if there are four person in first room, if represented in terms of fraction is equal to one fourth $\frac{1}{4}=0.25 m^2$ .

And, Area occupied by each person in second room,if there are six person in second room, if represented in terms of fraction is equal to one sixth $\frac{1}{6}=0.17 m^2$ .

So,→→ Area occupied by each person in which four people are residing>Area occupied by each person in which six people are residing.

→→So,Fraction with a lesser denominator has larger pieces(Larger area) than the fraction with a greater denominator smaller pieces(smaller area).
