To determine the total proportion of nonworking lights on the two streets, we need to calculate the sum of the fractions representing nonworking lights on each street.
On the first street, 2/3 of the lights do not work, and on the second street, 1/6 of the lights do not work.
To add these fractions, we first need to find a common denominator. In this case, the least common multiple of 3 and 6 is 6. So, we convert the fraction 2/3 to have the same denominator:
2/3 = (2/3) * (2/2) = 4/6
Now, we can add the fractions:
4/6 + 1/6 = 5/6
Therefore, the total fractional proportion of nonworking lights on these two streets is 5/6.
An electrical company decides to replace the lightbulbs and all the nonworking street lights on two specific streets. The company learns that 2/3 of the lights, do not work on the first street 1/6 of the lights do not work on the second street. What is the total fractional proportion of the nonworking lights on these two streets?
