Select proportional or not proportional to correctly classify the pair of ratios. 1.2/3 and 1.8/4.5

Gnesinka [82]

Answer:

Proportional.

Step-by-step explanation:

Find the cross products. If they are same, then they are proportional.

$\dfrac{1.2}{3} = \dfrac{1.8}{4.5}$

Cross multiply,

1.2 * 4 .5 = 3*1.8

5.40 = 5.4

So, they are proportional.

Multiply the numerator and denominator of 1.2/3 by 1.5

$\dfrac{1.2*1.5}{3*1.5}=\dfrac{1.8}{4.5}$

From this we come to know they are proportional

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.

Here’s another one free 50 points and brainiest, first come first serve!<br> 4x+5-10+3x=57

GarryVolchara [31]

So we have to simplify this equation:
4x+5-10+3x=57
Add like terms:
7x-5=57
Then add 5 to both sides:
7x=62
x=62/7
