What is the relationship between the ratios? 48/72 and 6/9 Drag and drop to complete the statement. The ratios are . proportiona

IrinaVladis [17]

Answer:

The Ratios are Proportional

Step-by-step explanation:

Let,

R1 = 48 / 72 ----- (1)

R2 = 6/9 ------ (2)

If we divide right hand side of above equation by 8, we get,

$R1 = (48/8) / (72/8)\\R1 = 6/9$

Therefore, it means that, in simplified form, both ratios are same and hence proportional.

R1 : R2 = 6/9 : 6/9

=. What does the expression (x+3)(9) represent? Why?

tresset_1 [31]

Because when you multiply the 9 by x you get 9x and when you multiply the 9 by 3 you get 27. So then your final answer would be 9x + 27.
