Explanation:
Fraction Simplifying
We are given the ratio 2 Km:3400 m. This can be written in fraction form as:
![\displaystyle (2\ km)/(3400\ m)](https://img.qammunity.org/2021/formulas/mathematics/college/qi2dcei9fj0nij0mpr9o9ewwkvsswx9k6h.png)
Since 2 Km = 2000 m:
![\displaystyle (2\ km)/(3400\ m)=\frac{2000\ \\ot{m}}{3400\ \\ot{m}}](https://img.qammunity.org/2021/formulas/mathematics/college/vnquvilnyca0lwat8lsnyydioqdna3hez7.png)
We need to simplify the fraction:
![\displaystyle (2000)/(3400)](https://img.qammunity.org/2021/formulas/mathematics/college/z1sr572lcnfrurjcbqd6a50wjqnnzt50nr.png)
We cancel out two zeroes, which is like dividing both numbers by 100:
![\displaystyle \frac{20\\ot{0}\\ot{0}}{34\\ot{0}\\ot{0}}](https://img.qammunity.org/2021/formulas/mathematics/college/6t3v5p8n4iocz8oif37fv93wt2h9kihh6j.png)
The remaining fraction is:
![\displaystyle (20)/(34)](https://img.qammunity.org/2021/formulas/mathematics/college/kuqr80qwl9rl6iib2irhh2zkc11rmayswn.png)
Dividing both by 2:
![\displaystyle (10)/(17)](https://img.qammunity.org/2021/formulas/mathematics/college/r4kr50nk23micwdrq7eoap3q6d5x0v0zrt.png)
Since the denominator is a prime number, no more simplifying is possible, thus the given ratio is equivalent to:
![\boxed{\displaystyle (10)/(17)}](https://img.qammunity.org/2021/formulas/mathematics/college/20ni43g8udpfn80f1clvqjw12pdfashzrf.png)
