This question is simple. Do not worry. I will get it done for you. What we need to do here is to divide 2/3 by 6 because you have 2/3 of the salad leftover and you want to split it among 6 friends. 6/1 is the same as 6 because if you divide 6 and 1, you get 6. Hence, 2/3 / 6/1. However, we need to flip the second fraction. So, 6 is the denominator and 1 is the numerator. When we do that, the question is now a multiplication question.
2/3 x 1/6 = 2/18
However, the fraction can be simplified by dividing both sides by 2.
2/2 x 18/2 = 1/9
Hence, each friend receives 1/9 of the salad.
