8/10 - 3/10 = x + 1 1/2\n5/10 = x + 1 1/2\n1/2 = x + 1 1/2\n-1 1/2 = x

just plug -1.5 in for x and see if it equals 1.5.       \n2 X -1.5 = -3                  -3 does not equal 1.5\nso the answer is false

7/5.\n\n(2/5)^2 = 4/25, then divide by (1/5) to get 4/5.\n\nAs for the rest, it's (-2) * (-3) / 10 = 6/10 = 3/5.\n\n3/5 + 4/5 = 7/5.

change the 4 to 4/1. \n\n4/1*-3/2= -12/6 and then you simplify\n\nfinal answer is -6.\n\nyes you can change -3/2 to -1.5 but you will find it easier in the long run to make the whole number (4) into a fraction. not all equations will be this simple and you won't be able to figure out what the next fraction is in your head.
