Sharing the Soda

Problem Source

Luogu P5706

Problem Description

Now there are $t$ millilitres of soda to be shared equally among $n$ classmates. Each classmate needs $2$ cups. You need to find out how many millilitres of drink each classmate gets (strictly to 3 decimal places), and how many cups are needed in total.

Input Format

One real number $t$ and one positive integer $n$, separated by a space.

Output Format

Output two lines.

The first line outputs a number with 3 decimal places: the amount of drink each classmate gets. The second line outputs a positive integer: the total number of cups needed.

Sample Input

500.0 3

Sample Output

166.667
6

Hint

• A single line mixes a decimal and an integer; cin can tell them apart automatically, but you must pick the right type for each variable yourself.
• "How much each person gets" is a division whose result is a decimal — think about what type the dividend should be.
• Keeping 3 decimal places needs format control (fixed and setprecision, from the header <iomanip>).
• The output is two lines: the first line is the amount per person, the second line is the number of cups.
• Check against the sample: 500.0 3 → first line 166.667, second line 6.

For all data, $0 \le t \le 10000$ with at most $3$ decimal places, and $1 \le n \le 1000$.
