a=144
b=48
c=60
d=132
This is what I got using my(online) calculator
The actual airplane wing is 24 times bigger than her first drawing.
24*4=96
The actual airplane wing is 96 inches long.
96/12=8
The actual airplane wing is 8 feet long.
The scale of her advertisement is 10 in : 96 in.
That reduces to 5 in :48 in.

Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.

So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.
