In the above Question the following information is given -

The length of two rods are 6m 75cm and 15m 50cm respectively .

Find the length of the longest tape which can measure these lengths .

Solution -

Here , these two rods measure 6m 75cm and 15m 50cm respectively .

Now ,

The length of the longest tape which can measure these lengths , can be found out by taking the HCF of the two rod lengths .

Rod 1 => 675 cm

Rod 2 => 1550 cm

675 ) 1550 ( 2

1350

____

200 ) 675 ( 3

600

____

75 ) 200 ( 2

150

____

50 ) 75 ( 1

50

___

25 ) 50 ( 2

2

____

0

Hence , 25 cm is th required length of the tape that can measure .

This is the required answer .
