Answer: m1 = 0.5
M2= 0.375
M3 = 2.25
M4 = 3.0
M5 = 13.5
M6 = 0.285
M7 = 7.0
Step-by-step explanation:
(20,40)-(15,30)=(5,10), m1=5/10=0.5
(18,48)-(12,32)=(6,16), m2=3/8=0.375
(72,32)-(27,12)=(45,20), m3=9/4=2.25
(60,20)-(45,15)=(15,5), m4=3.0
(243,18)-(27,2)=(216,16), m5=27/2=13.5
(24,84)-(18,63)=(6,21), m6=2/7=0.285...
(84,12)-(63,9)=(21,3), m7=7.0
The Answer to your problem is:
0.8
