Answer:

The product is the answer to a multiplication problem. You can find a product by a process called repeated addition, which is to say, by adding together the number of groups in the problem.

Answer:

$\frac{27}{20}$

Step-by-step explanation:

To find the number we can do the inverse operation to find it:

$\frac{2}{3}$ × n = $\frac{9}{10}$ - so we divide as an inverse function

$\frac{9}{10}$ ÷ $\frac{2}{3}$ = 27/20

Each of the 4 choices has been drawn step by step as follows:

the first transformation is drawn in light grey
the second transformation is drawn in dark grey
the third transformation is described as how it should be.

Choice I, picture I:
Rotate 180°, reflect over the x-axis, reflect over the line y=x

the last transformation should be : reflect with respect to the y-axis

Choice II, picture II:
Reflect over the x-axis, rotate 180°, reflect over the x-axis

the last transformation should be : reflect with respect to the y-axis

Choice III, picture III:
Rotate 180°, reflect over the y-axis, reflect over the line y=x

the last transformation should be : reflect with respect to the x-axis

Choice IV, picture IV:
Reflect over the y-axis, reflect over the x-axis, rotate 180°

the last transformation should be : rotate 180° CORRECT!

Answer: Reflect over the y-axis, reflect over the x-axis, rotate 180°
