the X represents closed circles
4 is what is knows as the factorial of 4.
4=4*3*2*1=24
The dimension of the document is 35 inches by 40 inches.
It is redrawn at a scale of 1 1/2 or 3/2 or 1.5
The dimension will be:
35 * 1.5 = 52.5 in
40 * 1.5 = 60 in
Then redrawn again at 1/4 or 0.25
52.5 * 0.25 = 13.125 in
60 * 0.25 = 15 in
So the final dimensions of the drawing is 13.125 in by 15 in
Because you are still multiplying the same values of the number you are multiplying and it's standard form
What I did is to add 0.52
+0.15
then try to find what could equal the same amount with 0.52
