Answer:
x=1
Step-by-step explanation:
this is because in this scale drawing they x2 when they are changing the numbers so you have to think what number x2 would give you 8 and that number is 1. so then you test it out and apply it to your scale drawing and they are 20 and 8
306/6 is 51 is you add one to one side and take away the other the six numbers become: 46, 48, 50, 52, 54, 56 as you added one to one side substituting the other you took away from, therefore the smallest would be 46.
