Question

Round 0.0695712 to 2 significant figures

Answer 1

Answer:

The number becomes $0.070$.

Step-by-step explanation:

Significant numbers: Significant figures are defined as the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value.

Here, we start counting significant figures at the first non-zero digit.

Rule for decimal number:

All zeros that are on the right of a decimal point are significant, only if, a non-zero digit does not follow them.

All of the zeros that are on the right of the last non-zero digit, after the decimal point, are significant.

The given number is $0.0695712$

As there is $5$ after $9$. So $1$ will be added to $9$.

So the number becomes $0.070$.
