Answer:
dd
Step-by-step explanation:
when you have two fractions that equal each other you want to solve by using cross multiply
What cross multiply is, is when you multiply diagonally so:
8/x=14/7
you would take 14*x and 8*7
14x=56 (you would then divide each side by 14)
x=4 (14/14=1, 56/14=4)
8/4=14/7
To check your work you could simplify
8/4=2
14/7=2
2=2, which is true
x=4
Hope this helps ;)
Answer: m1 = 0.5
M2= 0.375
M3 = 2.25
M4 = 3.0
M5 = 13.5
M6 = 0.285
M7 = 7.0
(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
