The modern rules of precedence would say to evaluate the sum in the parentheses first, then perform the division and multiplication (which have equal precedence) going left to right.
So the answer is:
3 × 3 = 9
Now the answer might have been different in the past. The division symbol (obelus) used to be treated more like the horizontal line in a fraction. It implied a grouping of everything before the division symbol which was then divided by the result of everything after the division symbol.
Of course this was back in the 17th century when the obelus was first used in a mathematical context. Today the answer would always be 9.

Only children use the divide symbol ÷ grownups use a vinculum.

Nine.
Do same level operations (multiplication/division or addition/,subtraction) left to right.
(6/2) * (1+2)
= 3 * 3 = 9
9 because 6/2=3 and 1+2=3 so 3x3=9
