Insert group in symbols to make the equation true 8+12/4*5=1

(8+12)/(4*5)=1

To insert a symbol in the equation to make it true, we need to determine which operation should be done first. This is done by following the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's analyze the equation step by step:

8 + 12 / 4 * 5 = 1

First, we perform the division:

8 + (12 / 4) * 5 = 1

Now, we evaluate the division in parentheses:

8 + (3) * 5 = 1

Next, we perform the multiplication:

8 + 3 * 5 = 1

Finally, we perform the addition:

8 + 15 = 1

However, 8 + 15 is not equal to 1.

Based on the given equation, there is no combination of parentheses or grouping symbols that can be inserted to make the equation true.
