The length of the first segment is 7 cm. 2 mm, it is 8 times longer than the second segment.

The length of the first segment is 7 cm. 2 mm, it is 8 times longer than the second segment. find the length of the second segment.

It is necessary to calculate the length of the second segment, it is known that it is 8 times longer than the first, the length of which is 7 cm 8 mm, therefore, in order to find out the length of the second segment, you need to translate cm into mm and divide by 8, for this we recall the theory: in 1 cm 10 mm;

7 cm 8 mm = 78 mm, now should be divided by 8, 78: 8 = 9.75 mm;

Answer: 9.75 mm;
