Comparison is an effort to compare two or more objects in terms of shape or size, or number  

Proportional Comparisons / Directly proportional are comparisons of two or more numbers where one number increases, the other numbers also increase at the same rate  

 Can be formulated  

 so that if:  

 x = 2  

 then  

 While the reversal value comparison / inversely proportional is the comparison of two or more numbers where one number increases, the other number decreases in value  

or when one value decreases at the same rate that the other increases  

 Can be formulated  

so that if:  

 x = 2  

 then  

Dan and Paul ratio of 13:5 ⇒ D:P = 13:5

Then :

Dan gives Paul £32 and the ratio 1:1

D-32 = P +32

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
