Question

what type of data type we will use for the value 0xFA9 in java​

Answer 1

Answer:

The smallest rational number by which \frac{1}{3}

3

1

should be multiplied so that its decimal expansion terminates after one place of decimal is?

Solution :

To get a terminating decimal digit we use 2m\times 3n2m×3n in the denominator.

The number of decimal digit is proportional to “m” and “n” the decimal digit is m if m > n and n if decimal digit is n.

If the denominator is 2, 5 or 10 we find the decimal digits termination after one place

So the smallest number that can be multiplies by \frac{1}{3}

3

1

is \frac{1}{10}

10

1

, as \frac{1}{10}

10

1

has 0.1.

It is the smallest decimal expansion that can be nothing is smaller than 1 except zero but that won’t be decimal.
