P is a rectangle with 40cm and a width of x cm q is a rectangle with the width of ym

we know that

the length of Q is 25% more than the length of p

so

length Q=1.25*40> 50 cm

the area of Q is 10% less than the area of p

Area Q=50*y

Area P=40*x

so

50*y=0.90*[40*x]> 50*y=36*x> x/y=50/36---> 25/18

the answer 

the ratio x:y is 25:18

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 6 -   17/5

= 30/5 - 17/5

= 13/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
