Question

45 M 78 CM - 23 M 91 CM​

Answer 1

Ответ:

45 м 78 см - 23 м 91 см = 21 м 83 см

Answer 2

Ответ:

Сначала переведем все метры в см

1м = 100 см

45 м = 45×100 = 4500 см

4500 + 78 = 4578 см

23 м = 23×100 = 2300 см

2300 + 91 = 2391 см

4578 - 2391 = 2187 см

2187 = 2187 ÷ 100 = 21,87 м = 21 м 87 см

Answer 3

To subtract the second measurement from the first measurement, you need to subtract the meters and centimeters separately.

First measurement: 45 meters 78 centimeters Second measurement: 23 meters 91 centimeters

Now, subtract the meters and centimeters separately:

Meters: 45 meters - 23 meters = 22 meters

Centimeters: 78 centimeters - 91 centimeters = -13 centimeters

Since you have a negative value in centimeters, you need to borrow 1 meter from the meters to make it positive:

22 meters - 1 meter = 21 meters 100 centimeters (from the borrowed meter) - 13 centimeters = 87 centimeters

So, the result is: 21 meters 87 centimeters.
