Suppose a carpenter's ruler was mark and 30 seconds will be the fraction and it's decimal equivalent for the mark on the ruler between 3/8 and 4/8

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
