Let
x--------> <span>the unknown scale size
we know that
N 1---------> 2.618
N 2---------> x
N 3---------> 1
N 4---------> 0.618
to obtain the size N 4 ----> multiply the size N 3 by 0.618
so
to obtain </span> the size N 2 ----> multiply the size N 1 by 0.618
size N 2=2.618*0.618------> 1.6179
x=1.618
the answer is
the unknown scale size is 1.618
To use the distributive property, we "distribute" a value on the outside of a set of parentheses to all of the values on the inside of the parentheses. For example...
6(3 + 9) = 6*3 + 6*9
For your problem, you only have one value 13.99, but we can split it apart to make it a little easier to work with (like with mental math). We can say that 13.99 is the same as 10 + 3.99. Now we can take it and multiply by 9 with the distributive property...
9(10 + 3.99) =
9*10 + 9*3.99 =
90 + 35.91 =
$125.91
