Because they show how big a number is, for example you cant just write '3' and say its three million, you need zeros to show how big it really is, i.e. 3,000,000.

Because
three, leading zeros are not significant and trailing zeros are significant if there is a decimal. trailing zeros are not significant if there is no decimal zeros in the middle of numbers are significant
Five. Zeros in between significant digits are significant and trailing zeros that are after the decimal are significant.
Yes - zeros in-between significant digits are significant.
Four. When the decimal point is expressed, trailing zeros are significant. Leading zeros are never significant.
Because
Just 1 The two zeros are placeholders- placeholders are not significant
three, leading zeros are not significant and trailing zeros are significant if there is a decimal. trailing zeros are not significant if there is no decimal zeros in the middle of numbers are significant
Five. Zeros in between significant digits are significant and trailing zeros that are after the decimal are significant.
Yes - zeros in-between significant digits are significant.
None of the zeros in that number are significant.
There are 4 significant zeros in the measurement 0.000 040 200 m. Zeros between significant digits are considered significant, as well as zeros to the right of the decimal point in a measured quantity.
Any number that is not zero is significant. However, zeros that appear between non-zeros are significant. Even more confusing is that leading zeros are not significant while trailing zeros are. So, it really depends on what you are looking at. And where the zeros are.
Leading zeros and trailing zeros in numbers that don't have a decimal point.
Well, honey, you've got your leading zeros, which are the zeros at the beginning of a number like 007. Then there are trailing zeros, which are the zeros at the end of a number, like 120. And last but not least, we've got interior zeros, which are the zeros sandwiched between non-zero digits, like in 506. Hope that clears things up for ya!
There are five significant figures. The two zeros between the 5 million and 1 thousand are significant: 15001000, because they are between other significant figures. They tell that those places have a certain value (other than 1,2,3 etc). The three zeros in the ones, tens and hundreds places are not significant, because they just indicate scale. Note that if it had said 15001000.0 then it could be said that those zeros are significant because they represent a specific value.
In any position other than before the first non-zero digitin an integer, after the last non-zero digit.Note that all the zeros in 250.0 are significant since the number, as expressed, is NOT an integer.
