How many significant figures are in 100?
If you are looking at this from a maths perspective, the 'significant figures' are the number of digits counting from the first non-zero digit, so the number of significant figures in 10.0 is three. You may be asked a question, and told to give the answer 'to three significant figures'. This would mean the answer would look something like '12.2' or '0.0254'. This is in contrast to decimal places, which refer to the number of digits after the decimal point. For example, the number 10.0 is quoted to one decimal place.
What is the number of significant figures in 87.5580?
That's 6. You count all the numbers but the last "0", as you don't need to have that to give the same result. 87.558 is the same as 87.5580
How do you add number using significant digits?
Adding numbers using only the significant digits can introduce inaccuracies, for example if you are adding pi ten times using 4 decimal places of pi the answer is 31.416 but the right answer is 31.4159 . . Subtracting can give quite bad errors especially when two nearly equal numbers are subtracted. So for subtraction it's best to use more significant figures and round the answer to the required number of digits afterwards.
Would you use grams or kilograms to weigh a spoon?
I would use grams because grams would give you more significant figures for the measurement than kilograms
Can you give me a clue for 'decimal'?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Adding zeros after the decimal point is wrong because they imply a degree of accuracy (significant figures) for which there is no justification.
How many significant figures are in 2.110?

What number has the greatest number of significant figures?
0.00684 has three significant figures The product of 7.6 x 1.246321 has two significant figures. 28623 has five significant figures. 1.20000 x 10-19 has six significant figures. Trailing zeroes after a decimal point are considered significant. In scientific notation, only the numbers before the multiplication symbol are considered significant.

What is the significant figures in 14525?
14525 has 5 significant figures (s.f) significant figures help mathematicians to summarise their answer for example to give an approximation if 3 significant figures was required then the answer would be 14500 if you were asked to give 1.1235678 to 4 s.f. then the answer would 1.124 (rounding up the last digit). I hopes this help

How do you round 0.007222 into 3 significant figures?
Non-zero numbers are always significant and leading zeros are never significant. So 0.007222 has 4 significant figures so rounding to 3 would give you 0.00722.
What is the number of significant figures in 87.5580?
That's 6. You count all the numbers but the last "0", as you don't need to have that to give the same result. 87.558 is the same as 87.5580

8.235
How do you change things in to significant figures?
The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
What significant figure does the number 001 give you?
