How many significant digits does the number 700 have?

700 has one significant figure which is 7.

Explanation: These are some rules for significant figures

•All non-zero digits are significant: 1,2,3,4,5,6,7,8,9

•Zero between non-zero digits are significant: They are three significant figures in 203.

•Leading zeros are not significant: There are two significant figures in 0.56.

•Trailing zero to the right of decimal are significant. There are four significant figures in 62.00

•Trailing zeros in a whole number with the decimal shown are significant: This makes "700." three significant figures.

•Trailing zeros in a whole number with no decimal shown are not significant: This makes 700 one significant figure.

In the number 700 there is only one significant figure.

Explanation:

How do I know this? Well, ya see, 7 is a nonzero digit. So, since it is a non zero digit, the significant digit of 700 is 7. To determine what numbers are significant and which aren't, use the following rules:

The zero to the left of the decimal value less than 1 is not significant.

All trailing zeros that are placeholders are not significant.

Zeros between non zero numbers are significant.

All non zero numbers are significant.

If a number has more numbers than the desired numbers of significant digits, the number is rounded. For example, 432,500 is 433,000 to 3 significant digits.

Zeros at the end of numbers which are not significant but are not removed, as removing would affect the value of the number. In the above example, cannot remove 000 in 433,000 unless changing the number into scientific notation.
