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.
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
