d)ii)8z=72
z=72/8
z=9
i)p+2 1/2 =5
p + 5/2=5
p=5 x 2/5
p=5
e)8:10::16:20
10 x 16=8 x 20
16=8 x 20 /10
16=16
L.H.S=R.H.S
g)perimeter of square=area of square
4s=2500
s=2500/4
s=685m
Therefore perimeter of square =685m
b)arrange in ascending order:- -2,0,2 1/2,0.5
-2,0,5/2,1/2
(make the denominators same by taking L.C.M=2)
-4/2,0,5/2,1/2
ascending order = -4/2 , 0 , 1/2 , 5/2
