You can use the following basic syntax to return a blank instead of a zero when using formulas in Google Sheets:

```=IF(B2/C2=0, "", B2/C2)
```

This particular formula attempts to divide the value in cell B2 by the value in cell C2.

If the result is zero, then Google Sheets returns a blank.

Otherwise, it returns the result of B2 divided by C2.

The following example shows how to use this formula in practice.

Suppose we have the following dataset that shows the total sales and returns for various products:

Suppose we type the following formula into cell D2 to calculate the return rate for product A:

`=B2/C2`

If we click and drag this formula down to every cell in column D, we’ll see that some of the results are equal to zero:

To return a blank value instead of a zero, we can type the following formula into cell D2:

`=IF(B2/C2=0, "", B2/C2)`

We can then click and drag this formula down to every remaining cell in column D:

Notice that every cell where the formula would return a zero now returns a blank value instead.
