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?

Result

n =  2

Solution:

A=div 62={1,2,31,62} B=div 102.2=div 22={1,2,11,22} n=AB={1,2}=2 A = div \ 62 = \{ 1, 2, 31, 62 \} \ \\ B = div \ 10 \cdot 2.2 = div \ 22 = \{ 1, 2, 11, 22 \} \ \\ n = |A \cap B| = | \{ 1, 2 \} | = 2 \ \\



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
