Well in order to solve the first one you would want to find things in the numerator and the denominator that are similar; such as 9x and 15x, or 2x squared and x square. Then you should divide the numbers
4 1/6 is your answer because 6* 4 = 24 so then there is just one more left over which makes the 1/6
Answer:
-4 x -4 = -16
4 x 4 = 16
^2 or to the power of 2 basely means 4 times itself, because 2.
To solve 2/3 of 12 we need to divide 12 by 3 which is 4 so then we need to do 4 x 2 which is 8. Hope I helped.
