The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". The first figure to be discarded is '6' and as this is greater than 5 then the previous figure (4) is increased by 1 (to 5). 29.46 when rounded off to three significant figures is 29.5.
5 kilometers. A significant figure is anything except a 0, before a decimal point.
The rules for rounduing off numbers are as follows :- 1) If the first figure to be discarded is 5 or more, then the previous figure is increased by 1. Example : 5.1935 = 5.194 (4sf) = 5.19 (3sf) = 5.2 (2sf) = 5 (1sf) 2) Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure. 1347 . . . when rounded to 3 significant figures then the 7 is discarded so 4 increases to 5. Thus, 1347 becomes 1350 (3sf). When rounded to 2 significant figures it becomes 1400 and to one significant figure 1000.
5 of them.
One significant figure.
The number 46313 rounded to 1 significant figure is 50000. The significant digit is 5, so the number is rounded up to the nearest power of 10.

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**.
1.4 since the no after the 3 is greater than 5.
It is then 30,000 rounded to 1 significant figure
At least 1 and at most 7. It could be 3,999,999.9 rounded to 7 significant figures; It could be 3,999,999 rounded to 6 significant figures; It could be 4,000,015 rounded to 5 significant figures; It could be 4,000,429 rounded to 4 significant figures; It could be 3,999,999 rounded to 3 significant figures; It could be 4,049,999 rounded to 2 significant figures; It could be 4,492,467 rounded to 1 significant figure.

The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.
0.000892 to 1 significant figure is 0.0009 (1st significant figure is the first non-digit from the left, where in this case you can omit the number 2 since it will make no difference to the answer)
1 teaspoon = 5 ml.5 /0.8 = 6.25 or 6 rounded to one significant figure.
Oh, dude, rounding 468 to one significant figure is like making it sound fancier but actually simpler. So, 468 would be rounded to 500 because the first significant figure is 4, and we're just like, "Eh, close enough, let's round up." So yeah, 468 becomes 500 when you're all about that one significant figure life.
