Graham and Julia each estimate the quotient of 4,875÷57 . Graham estimates that the quotient is about 80 . Julia estimates that the quotient is about 800 .Whose estimate is more reasonable?

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.
