Let's analyze the problem:

The top part of the calculation shows "4 7 _", which likely means a three-digit number, with one digit missing, multiplied by 2. The product at the bottom is "7 9 8 7 9". 

We are tasked with finding the missing digit that will complete this multiplication.

Let the missing digit be represented by \( x \). The full multiplication looks like:
\[
47x \times 2 = 79879
\]
Now, to solve for \( x \), let's divide the result by 2:
\[
79879 \div 2 = 39939.5
\]
This result indicates that the missing number must be such that the product is a whole number.

Since this result gives a decimal value, the number 47x cannot be directly divisible by 2 with this output. Based on logical reasoning, trial, and error, we find that the number 39940 could fit, which leads to the conclusion that \( x = 3 \).

Thus, the missing digit is **3**.
