Final answer:

To find the fraction of children with red or brown hair in Marci's family, we add the fractions of children with red hair and brown hair. The answer is 4/6 or 2/3.

Step-by-step explanation:

  • To find the fraction of children that have red or brown hair, we need to add the fractions of children with red hair and brown hair together.
  • From the given information, 1/6 of the children have red hair and 1/2 of the children have brown hair.
  • Adding these fractions, we get 1/6 + 1/2 = 1/6 + 3/6 = 4/6.
  • Therefore, 4/6 or 2/3 of the children have red or brown hair.

Answer 4/6 (or 2/3) of the kids have red or brown hair.

Step-by-step explanation:
For this problem, all we have to do is add!

We know that 1/3 (or 2/6) of the children have blonde hair
We know that 1/6 of the children have red hair
We know that 1/2 (or 3/6) of the children have brown hair

To find out how many children have red OR brown hair, we need to add the fractions together

1/6 + 3/6 = 4/6

If we simplify 4/6, we get 2/3


Hope this helps!
