Multiply −1 1/6 by 7. Write the answer as a mixed number.(1 point)
To multiply -1 1/6 by 7, first convert -1 1/6 to an improper fraction:
-1 1/6 = -(6/6 + 1/6)
= -(7/6)
Now, we can multiply -(7/6) by 7:
-(7/6) x 7
= -7 x (7/6)
= -49/6
To convert the improper fraction -49/6 back to a mixed number, divide the numerator by the denominator:
49 ÷ 6 = 8 remainder 1
So the mixed number is -8 1/6.
Of the cars in a used-car lot, 2/5 are the color gray. 1/3 of the gray cars are electrically powered vehicles. What fraction of the cars on the lot are both gray and electrically powered? Leave your answer in simplified fraction form
To find the fraction of cars on the lot that are both gray and electrically powered, we need to multiply the fractions representing the proportion of gray cars and the proportion of electrically powered gray cars.
The fraction representing the proportion of gray cars is 2/5.
The fraction representing the proportion of electrically powered gray cars is 1/3.
To find the fraction of cars that are both gray and electrically powered, we multiply these fractions:
(2/5) x (1/3) = 2/15
Therefore, 2/15 of the cars on the lot are both gray and electrically powered.
