Help with this question I also need explanation on how to do it!

C. It is correct because 1 7/9 x 3/8 equals 2/3

Step-by-step explanation:

- First we need to figure out if the solution is correct or incorrect. To do this, we will flip the fraction and multiply it. For example...

2/3 x 8/3 = 16/9 = 1 7/9

- Now we must determine which of the two correct options is correct. Lets try C.

You need to take 16/9/9 x 3/8 = 2/3. As you can see, this is correct and works.

- Hope this helps! If you would like a further explanation please let me know.

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
