Segments

Line segments 62 cm and 2.2 dm long we divide into equal parts which lengths in centimeters is expressed integer.

How many ways can we divide?

Correct answer:

n =  2

Step-by-step explanation:

$$\begin{gathered} A=div62=\{1,2,31,62\} \\ B=div10\cdot 2.2=div22=\{1,2,11,22\} \\ n=\mathrm{\mid }A\cap B\mathrm{\mid }=\mathrm{\mid }\{1,2\}\mathrm{\mid }=2 \end{gathered}$$
