How do you solve 1/12 times 20? and why is it 5/3

To solve this, you have to do the following.

1/12 X 20
You can lower the values of 12 and 20 by dividing with 2
Now it will be
1/6 X 10
Again you can divide it by 2
=>1/3X5
As you can no longer divide you multiply 5 times 1
The final Answer is
5/3

The answer is 1 because you have to flip the sign when dividing by negative number and 3
