You can rewrite this as (-0.7+0.15) divided by (-0.125). That can be simplified to 0.8 divided by negative 0.125. Keep in mind that 0.125 is equal to one eighth. Using that knowledge, we can rewrite it as 0.8 times negative one-eighth. We take the reciprocal of 1/8 which is 8.
0.8 times negative 8 is negative 6.4
