Fill in the missing number.

% of 19 = 0.38

it is wrong, it is 2

I apologize for the mistake. You are correct, the missing number is 2.

To fill in the missing number, we need to find what percentage represents 0.38 of the number 19.

To do this, we can set up a proportion:

x / 19 = 0.38 / 100

Where x is the missing number.

To solve for x, we can cross-multiply and then divide:

x * 100 = 0.38 * 19

x * 100 = 7.22

Dividing both sides by 100:

x = 7.22 / 100

x = 0.0722

Therefore, the missing number is 0.0722.

The missing number is 7.
