Work out 4/5 X 1 2/9
Give your answer as a fraction its simplest form.

Step-by-step explanation:

To solve this problem first change the mixed number into an improper fraction.  

1 2/9 --> 1 = 9/9 --> 9/9 + 2/9 = 11/9

Then, simply multiply the numerator and denominator of each fraction.

4 * 11 = 44

——————

5 * 9  = 45

44/45

Hope it helps :) and let me know if you want me to elaborate.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
