Do an estimate first: 0.626 is roughly 0.6 which is ⅗ and ⅗ of 75 is 45, so the answer is close to 45.

Multiplying, ignoring the decimal points: 469500. The answer is 46.95 because it’s close to the estimate 45.

Also, the number of digits following the decimal point is 1+3=4. So we get 46.9500 or 46.95.
