Answer:
Proportional.
Step-by-step explanation:
Find the cross products. If they are same, then they are proportional.
[tex]\dfrac{1.2}{3} = \dfrac{1.8}{4.5}[/tex]
Cross multiply,
1.2 * 4 .5 = 3*1.8
5.40 = 5.4
So, they are proportional.
Or
Multiply the numerator and denominator of 1.2/3 by 1.5
[tex]\dfrac{1.2*1.5}{3*1.5}=\dfrac{1.8}{4.5}[/tex]
From this we come to know they are proportional
Or
1.2 : 3 :: 1.8 : 4.5
Product of means = 3*1.8 = 5.4
Product of extremes = 1.2*4.5 = 5.4
Product of means = product of extremes. So, they are proportional.
