What is the scale factor of 3,6 and 4.5, 9
fredd [130]
To determine scale factor, we have to see what the common factor we multiply each term by in order to get the other two terms. To do this, we have to divide the corresponding values: 4.5/3 = 1.5. 9/6 = 1.5. Thus, since both pairs of numbers produced the same factor, it is 1.5

Multiply 11 by 4.90909091 and you get 54

Multiply 8 by 4.90909091 and you get 39.3

if you multiply by 4.9 you get 39.2
