Insert any operator on the blank to make the equation true. Use the symbol only once .25 ____ .4 ____ .05 = .2

To insert an operator on the blank to make the equation true, we need to find an operation that makes the left side of the equation equal to the right side, which is 0.2.

Let's evaluate the left side of the equation step by step:
First, we have 0.25.
Second, we need to perform an operation on 0.25 and 0.4 that yields a result of 0.2.

To find the operation, we can subtract 0.4 from 0.25:
0.25 - 0.4 = -0.15

However, this result is not 0.2. Therefore, subtraction is not the correct operation.

Next, let's try addition:
0.25 + 0.4 = 0.65

Again, this result is not 0.2. Hence, addition is not the correct operation.

Lastly, let's attempt multiplication:
0.25 × 0.4 = 0.1

This result is also not 0.2. Thus, multiplication is not the correct operation.

Since none of the operations (subtraction, addition, or multiplication) yield a result of 0.2, there is no correct operator to insert into the blank to make the equation true.
