Perform the indicated operation - 1/6 + 5/6

Answer: 2/3

Step-by-step explanation: To add like fractions or fractions that have the same denominator, simply add the numerators and keep the original denominator.

So here, if we add the numerators, we have - 1 + 5 which gives us 4 and we put this over our original denominator, 6.

So - 1/6 + 5/6 simplifies to 4/6.

Notice however that 4/6 is not in lowest terms so we need to divide the numerator and the denominator by their greatest common factor of 2 to get 2/3 which is written in lowest terms.
