Answer:
Step-by-step explanation:
Turn -9 into a fraction to get -9/1
Then multiply both fractions, so
-9/1 x 7/9
To work that out, you multiply the top number of each fraction by the bottom number of each fraction. In this case, that gives you
-9 x 7 / 1 x 9 which is equal to
-63/9
Simplify that to get -7
