First one is -1/9
Top: 1/6x36=6 minus 7 = -1
Bottom: 1/5x25=5 plus 4 = 9 so, -1/9
Second one is 40/7
Top: -5 squared is 25 minus (-50) = 75 +5 =80 (the two negatives mean you add the 25 and 50, -(-50) is same as +50)
Bottom: -5 squared is 25 plus (-10) = 15 -1 =14 (adding the negative 10 is same as subtraction)
Now you have 80/14, when simplified as far as it can go you get 40/7 (just divide by 2)
Hope that made some sense
EDIT: I just read the rest of the other posts and saw you figured it out. :thumbsup:
It actually took me a second, I haven't done math in a while and the last was all calc so I forget how to do fractions and the order of operations lol.
