Answer :

To work out the sum of 0.34 million and 5.8 thousand, let's break the problem down into clear, manageable steps:

### Step 1: Convert 0.34 million to thousands
To begin with, we need to convert 0.34 million to the same unit as 5.8 thousand, so we can easily add them together. We know that:
1 million = 1000 thousand

Therefore:
0.34 million = 0.34 1000 thousand

Multiplying the two values together:
0.34
1000 = 340 thousand

So, 0.34 million is equal to 340 thousand.

### Step 2: Add the converted value to the given thousands
Now that we have converted 0.34 million to 340 thousand, we can add it to the given value of 5.8 thousand.

So, we have:
340 thousand + 5.8 thousand

Adding these two values together:
340 + 5.8 = 345.8 thousand

### Final Answer
Thus, the sum of 0.34 million and 5.8 thousand is 345.8 thousand.
