Answer:

Step-by-step explanation:

A dilation is something that enlarges or shrinks an existing figure, retaining all angle measures. The two figures will be similar, not congruent.

A dilation of 1/2 (which is less than one) will make a figure smaller. You divide each coordinate point by two

(x, y) → ( $\frac{1}{2}x, \frac{1}{2}y$ )

Convert mixed number to improper fraction:

$1\dfrac{3}{4}=\dfrac{1\cdot4+3}{4}=\dfrac{4+3}{4}=\dfrac{7}{4}\\\\4\dfrac{1}{6}=\dfrac{4\cdot6+1}{6}=\dfrac{24+1}{6}=\dfrac{25}{6}\\\\1\dfrac{3}{4}\times4\dfrac{1}{6}=\dfrac{7}{4}\times\dfrac{25}{6}=\dfrac{7\times25}{4\times6}=\dfrac{175}{24}=\dfrac{168+7}{24}=7\dfrac{7}{24}$
