Frank needs to convert this scale drawing from 1 box equal 4 in to the scale of 1 box equals 2 . The width of the scale drawing shown is 3 boxes. What will the width of in boxes of the new drawing
If 1 box equals 4 inches in the original drawing, then the width of the original drawing is 7 blocks * 4 inches/block = <<7*4=28>>28 inches.
If 1 box equals 2 inches in the new drawing, then the width of the new drawing is 28 inches / 2 inches/block = <<28/2=14>>14 blocks. Answer: \boxed{14}.

You're welcome! If you have any more questions, feel free to ask.
To solve this problem, we will first find the width of the current drawing in inches, and then convert it to the new scale.
Given that the current width of the drawing is represented by 7 blocks, and each block is equal to 4 inches, we can find the width in inches as follows:
Current width in inches = 7 blocks * 4 inches/block = 28 inches
Now, we need to convert this width to the new scale of 1 box equals 2 inches. To do this, we will divide the current width in inches by the conversion factor:
New width in boxes = Current width in inches / (Conversion factor of 1 box = 2 inches)
New width in boxes = 28 inches / 2 inches = 14 boxes
Therefore, the width of the new drawing will be 14 boxes.
