Question

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)

Answer 1

To find the total fractional portion of the nonworking lights on both streets, we need to combine the fractions for 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.

To combine these fractions, we need to find a common denominator. The least common multiple of 3 and 6 is 6.

Converting the fractions to have a denominator of 6:
2/3 x 2/2 = 4/6
1/6

Adding the fractions together:
4/6 + 1/6 = 5/6

Therefore, the total fractional portion of the nonworking lights on both streets is 5/6.
