round the number its greatest place value then multiply

Question

6.3 x 39

Answer 1

To round the numbers to their greatest place value:

1. 6.3 rounds to 6 (the greatest place value is the ones place).
2. 39 rounds to 40 (the greatest place value is the tens place).

Now, multiply the rounded numbers:

\( 6 \times 40 = 240 \)

So, the result of rounding the numbers and then multiplying is 240.
