How do you insert grouping symbols to make this equation true? 9 plus 9 divided by 3 times 5 minus 3 = 12
[(9 + 9) / 3] * (5 - 3) = 12
16/2*4-3
To solve this equation and make it true, you need to insert grouping symbols (parentheses, brackets, or braces) in the correct places. Here's the step-by-step explanation:
1. According to the order of operations (PEMDAS/BODMAS), start by simplifying any calculations inside parentheses first.
2. Begin by inserting parentheses to group the division part:
9 + (9 ÷ 3) × 5 - 3 = 12
3. Now, simplify the division inside the parentheses:
9 + (3) × 5 - 3 = 12
4. Apply multiplication next:
9 + 15 - 3 = 12
5. Add and subtract from left to right:
24 - 3 = 12
6. Finally, solve the subtraction:
21 = 12
Since the equation 21 = 12 is false, it is not possible to insert grouping symbols to make the original equation true.
