The fraction of nonworking lights on the first street is 2/3, and the fraction of nonworking lights on the second street is 1/6.
To find the total fractional portion of nonworking lights on these two streets, we need to add these fractions together.
2/3 + 1/6
To add these fractions, we first need to find a common denominator. The common denominator of 3 and 6 is 6.
2/3 + 1/6 = (2 * 2)/(3 * 2) + 1/6 = 4/6 + 1/6 = 5/6
Therefore, the total fractional portion of the nonworking lights on these two streets is 5/6.
