Question

12м 43см +4м 47см +5м 53см​

Answer 1

Ответ:

$21.37m$

Пошаговое объяснение:

12м 43см+4м 47см+5м 53см

$12m \: \: 43cm + 4m \: \: 47cm = 16m \: \: 90cm$

$16m \: \: 90cm + 4m \: \: 47cm = 20m \: \: 137cm = 21m \: \: 37cm = 21.37m$

Answer 2

To add these lengths together, you can add the meters and centimeters separately.

Meters: 12m + 4m + 5m = 21 meters Centimeters: 43cm + 47cm + 53cm = 143 centimeters

Now, you can convert the excess centimeters to meters if necessary. Since there are 100 centimeters in 1 meter, you have 143 centimeters, which is 1 meter and 43 centimeters.

So, the total length is 21 meters and 1 meter 43 centimeters, which is 22 meters and 43 centimeters.
