To multiply 82 by -13, you would use the basic multiplication algorithm. Here is the work:

82
×(-13)
------
-984 (multiply 82 by -13: 82 × -13 = -1,066)
0 (add a 0 at the end for the placeholder)
------
-1,066

Therefore, 82 multiplied by -13 equals -1,066.

To multiply -116 by 7, we use the basic multiplication algorithm. Here is the work:

-116
× 7
------
-812 (multiply 116 by 7: 116 × 7 = 812)
+0 (add a 0 at the end for the placeholder)
------
-812

Therefore, -116 multiplied by 7 equals -812. As a mixed number, this would be written as -116/1 or simply -812.

To multiply -1 1/6 by 7, we first convert the mixed number into an improper fraction. Here is the work:

-1 1/6 = -7/6

Next, we multiply -7/6 by 7:

-7/6 × 7 = -49/6

Now, we need to express the answer as a mixed number. Dividing the numerator (-49) by the denominator (6), we get:

-49 ÷ 6 = -8 remainder 1

So, the mixed number representation of the answer is -8 1/6.

To calculate the fraction of cars on the lot that are both gray and electrically powered, we need to divide the number of gray and electrically powered cars by the total number of cars on the lot.

The number of gray and electrically powered cars is given as 13. The total number of cars on the lot is given as 154.

So, the fraction of cars that are both gray and electrically powered is:

13/154

This fraction cannot be simplified any further, so the answer is 13/154.

To calculate the fraction of cars on the lot that are both gray and electrically powered, we need to multiply the fraction of gray cars by the fraction of gray cars that are electrically powered.

The fraction of gray cars is given as 2/5. The fraction of gray cars that are electrically powered is given as 1/3.

Multiplying these fractions together, we get:

(2/5) * (1/3) = 2/15

Therefore, the fraction of cars on the lot that are both gray and electrically powered is 2/15.
