There is some ambiguity in the expression you have provided because of the order of operations.

The expression can be interpreted in two ways, depending on whether you apply the division operation first or the multiplication operation first:

If you apply the division operation first:

6 ÷ 2(1+2) = 6 ÷ 2(3)

= 6 ÷ 6

= 1

If you apply the multiplication operation first:

6 ÷ 2(1+2) = 6 ÷ 2(3)

= 6 ÷ 6

= 1

According to the order of operations, when there are no parentheses to indicate otherwise, multiplication and division should be done before addition and subtraction. In this case, since multiplication and division are of the same precedence, you should perform them from left to right.

Therefore, the final answer depends on how you interpret the expression, and it could be either 1 or 9. To avoid ambiguity, it's always best to use parentheses to clearly indicate the order of operations.
