Answer:
The answer is 1 : 3 : 2
Step-by-step explanation:
First, you have to make them into same unit by converting it into km or m :
1 km = 1000 m
0.007 km = 7 m
0.021 km = 21 m
7 : 21 : 14
OR
14 m = 0.014 km
Then you can simplify it by 7 :
m,
7 : 21 : 14
= 1 : 3 : 2
OR
km,
0.007 : 0.021 : 0.014
= 0.001 : 0.003 : 0.002
= 1 : 3 : 2
(take note: in ratio, it is better to put it in whole number form rather than decimal form)

There is no choice of integers

such that the left hand side is a rational number.

Leisure means happy place or a free space or in this case "Freetime"!
A two-way frequency table allows you to organize several things, but usually two pieces of data, known as bivariate data. These two-way frequency tables examine the relationships between two pieces of data, them being the category values. A common thing they are used for is to observe survey results and opinions from others. The answer to your statement would be that it allows you to organize bivariate data, if you are looking at the question from my point of view and context. I hope that surely helped, ask me for more questions!
(0.2)² = 1/25 = 0.04, (0.05)² = 1/4 = 0.25
i hope i helped :))
