Insert parentheses to make this number sentence true 81+19\25=9

You only have three numbers on the left, so the only possible expressions are

(81+19)/25 = 4
81 + (19/25) = not an integer

You sure you want a 9 on the right?

To make the number sentence true, we need to insert parentheses to clarify the order of operations. The given number sentence is:

81 + 19 ÷ 25 = 9

To ensure that the division is performed before the addition, we can add parentheses around the division operation.

81 + (19 ÷ 25) = 9

Now, let's calculate the value within the parentheses:

19 ÷ 25 = 0.76

Now we can substitute the value back into the number sentence:

81 + 0.76 = 9

However, this resulting number sentence is not true. There seems to be a mistake or typo in the original number sentence. Please double-check the equation or provide any additional information available.
