Evaluate a ratio of widths and a ratio of lengths. Are they the same?
No, see solution.
Practice makes perfect
We are asked to determine if the temporary tattoo is a dilation of the original design. To do this, we will compare a ratio of widths and a ratio of lengths. If they turn out to be equal, then we have a dilation.
Temporary Width/Original Width? =Temporary Length/Original Length
Let's evaluate these ratios using the given dimensions.
1.2/2.5? =1.25/3
⇓
0.48≠0.42
Since the ratios are not equal, the temporary tattoo is not a dilation of the original design.
