it's a tie because both responses correctly calculate the scale factor of 1.5 divided by 4 equals 0.375 and accurately apply it to the visible original measurements to give the new dimensions for the big star (0.75 by 0.56 inches) and the little star (0.43 by 0.32 inches) in the Photoshop document.
Both responses get it right since they each work out the scale factor correctly - taking 1.5 and dividing it by 4 to get 0.375 - and then use that number properly on the original measurements you can see. This gives you the right new sizes for your Photoshop document: the big star comes out to 0.75 by 0.56 inches, while the little star ends up at 0.43 by 0.32 inches.
