Answers
To add : 12 km 125 m 9 cm, 14 km 940 m 78 cm , 785 m 35 cm
First solving 12 km 125 m 9 cm
12 km 125 m 9 cm = 12 km + 125 m + 9 cm
= 12 km + 125( 100 cm ) + 9 cm
= 12( 1000 m ) + 12500 cm + 9 cm
= 12000( 100 cm ) + 12500 cm + 9 cm
= 1200000 cm + 12500 cm + 9 cm
= 1212509 cm
Then, solving 14 km 940 m 78 cm,
14 km 940 m 78 cm = 14 km + 940 m + 78 cm
= 14 km + 940( 100 cm ) + 78 cm
= 14( 1000 m ) + 94000 cm + 78 cm
= 14000 ( 100 cm ) + 94000 cm + 78 cm
= 1400000 cm + 94078 cm
= 1494078 cm
Now, solving 785 m 35 cm,
785 m 35 cm = 785 m + 35 cm
= 785( 100 cm ) + 35 cm
= 78500 cm + 35 cm
= 78535 cm
Therefore,
12 km 125 m 9 cm, 14 km 940 m 78 cm , 785 m 35 cm = 1212509 cm + 1494078 cm + 78535 cm = 2,785,122 cm
Method 2 :
Adding all cms = 9 cm + 78 cm + 35 cm
= 122 cm
= 1 m + 22 m
Adding all ms = 125 m + 940 m + 785 m
= 1850 cm
= 1 km + 850 m
adding all kms = 12 km + 14 km
= 26 km
Therefore,
12 km 125 m 9 cm, 14 km 940 m 78 cm , 785 m 35 cm = 26 km + 1 km + 850 m + 1 m + 22 cm
12 km 125 m 9 cm, 14 km 940 m 78 cm , 785 m 35 cm = 27 km + 851 m + 22 cm
12 km 125 m 9 cm, 14 km 940 m 78 cm , 785 m 35 cm = 27 km 851 m 22 cm
Convert all to cm:
12 km 125 m 9 cm = ( 12 x 1000 x 100 ) + (125 x 100) + 9
12 km 125 m 9 cm = 1,200,000 + 12,500 + 9
12 km 125 m 9 cm = 1.212,509 cm
14 km 940 m 78 cm = (14 x 1000 x 100) + (940 x 100) + 78
14 km 940 m 78 cm = 1,400,000 + 94,000 + 78
14 km 940 m 78 cm = 1,494,078 cm
785m 35cm = (785 x 100) + 35
785m 35cm = 78500 + 35
785m 35cm = 78535
Add the numbers:
12 km 125 m 9 cm + 14 km 940 m 78 cm + 785m 35cm = 1.212,509 + 1,494,078 + 78535
12 km 125 m 9 cm + 14 km 940 m 78 cm + 785m 35cm = 2,785,122 cm
Convert cm back to km. m, cm:
2,785,122 cm = 27 km 851 m 22 cm
Answer: 27 km 851 m 22 cm
