An easy way to find this is to look at the cross section, and see where the lines meet
The first one A 7/2
You can just round up 6.75 -> 7 and 1.67->2
hi <3
lets call the unknown number 'x' for now and form an equation from what we know
1/3(x-9) = 15
now multiply both sides by 3
x - 9 = 45
add 9 to both sides
x = 54
hope this helps :)
The scale factor would be
So the scale factor is
1.6
