An electrical company decides to replace the lightbulbs in all of the nonworking street lights on two specific streets. The company learns that 2/3 of the lights do not work on the first street and 1/6 of the lights do not work on the second street. What is the total fractional portion of the nonworking lights on these two streets?(1 point
To find the total fractional portion of nonworking lights on the two streets, we need to add the fractions representing the nonworking lights on each street.
On the first street, 2/3 of the lights do not work.
On the second street, 1/6 of the lights do not work.
Adding these fractions gives us:
2/3 + 1/6
To add these fractions, we need to find a common denominator. The least common multiple of 3 and 6 is 6.
2/3 + 1/6 = (2/3)(2/2) + 1/6
= 4/6 + 1/6
= 5/6
Therefore, the total fractional portion of nonworking lights on these two streets is 5/6.
