Answer:

x = <u>12/5</u>

Step-by-step explanation:

Since the original is 10 and the second is 6, that means that the scale is 10:6 or 5:3.  It can also be related as %60 of the length.

<u>Step 1:  Make an equation</u>

10/6 = 4/x

<u>Step 2:  Cross Multiply</u>

10x = 24

<u>Step 3:  Divide</u>

10x / 10 = 24 / 10

24/10 = 12/5

x = 2.4
