The  answer is

Explanation:-

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.

All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.

All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.

All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.

The rule apply for multiplication and division is :

The least precise number determines the number of significant figures in the answer.

For

As the figure 3.47 contains 3 significant digits and 6.7 contains 2 significant digits, the answer must contain 2 significant digits.

Thus the answer is
