Evaluate -6(7/6)+2(1/3)=

-6.333333... OR -19/3

In the problem: -6(7/6) + 2(1/3) Let's only worry about the left of the equal sign for now.

-6(7/6) we have to simplify this. So what we do is we multiply -6(7) and leave the denominator the same so -6(7/6) is -7.

Now we simplify the right part of this problem.

2(1/3) just like the 1st time, we have to simplify this. So what we do is we multiply 2 and 1 together and leave the denominator the same. So, 2(1) is 2 and leave the denominator the same so the answer is 2/3

Now add them together.

-7 + 2/3 = 6.333...
