There were 336 people at a concert. If 2thirds were children, how many chairs are needed for the adults?

2/3 children means 1/3 adults.

Therefore multiply 336 * 1/3 =
OR divide 336/3

To find out how many chairs are needed for the adults, we first need to calculate the number of children at the concert.

We know that 2/3 of the 336 people were children. To calculate this, multiply 336 by 2/3:

336 * (2/3) = 672/3 = 224 children

Now, to find the number of adults, subtract the number of children from the total number of people:

336 - 224 = 112 adults

Since each person requires one chair, the number of chairs needed for the adults is equal to the number of adults, which is 112. Therefore, 112 chairs are needed for the adults at the concert.
