To round 1467 to three significant figures, we start counting from the left until we have three digits: 1, 4, and 6. The digit after the third significant figure is 7, which is greater than or equal to 5, so we round up the last significant figure. Therefore, 1467 rounded to three significant figures is 1470.
To convert the number 0.004758 to three significant figures, we need to round it off appropriately. Identify the significant figures: The given number, 0.004758, has 5 significant figures. Determine the significant figures based on the three most significant digits: The three most significant digits in 0.004758 are 4, 7, and 5. Round the number: Look at the digit immediately after the third significant figure, which is 7. Since 7 is 5 or greater, we round up the third significant figure (5). Apply rounding: The number rounded to three significant figures is 0.00476. Therefore, 0.004758 rounded to three significant figures is **0.00476**.

It isn't clear what the question is. If you are supposed to multiply or divide, and if by "signification figures" you mean significant digits, do the multiplication (or division), then round to three significant digits - since the least-precise of the numbers only has three significant digits.
Three - zeros between significant digits are significant.
