Answer:
7
Step-by-step explanation:
-7 x -7 x [tex]\frac{1}{7}[/tex]
It's easierst to start with -7 x [tex]\frac{1}{7}[/tex]
In order to easily multiply we re-write as -7 as - [tex]\frac{7}{1}[/tex] to make the multiplication easier. So we have:
- [tex]\frac{7}{1}[/tex] x [tex]\frac{1}{7}[/tex] we multiply straight across so we end up with
- [tex]\frac{7}{7}[/tex] which is the same as -1
Now we have:
-7 x -1 a negative multiplied by a negative is a positive so:
-7 x -1 = 7
