Question

4м45см + 12м56см 10м - 2м43см

Answer 1

4м 45см + 12м 56см = 16м 101см = 17м 1см
10м - 2м 43см = 9м 100см - 2м 43см = 7м 57см

Answer 2

To perform the given arithmetic operations, we need to add and subtract the given measurements. Let's start with addition:

4м 45см + 12м 56см

To add the meters, we have 4m + 12m = 16m.

Next, we add the centimeters: 45cm + 56cm = 101cm.

However, since there are 100 centimeters in 1 meter, we need to convert the 101cm into meters and centimeters.

Dividing 101cm by 100cm/m gives us 1m and a remainder of 1cm.

Therefore, the sum is 16m 1см.

Now let's move on to subtraction:

10м - 2м 43см

To subtract, we subtract the meters and then the centimeters.

10m - 2m = 8m.

Next, we subtract the centimeters: 0см - 43см.

Since we can't subtract 43 from 0, we need to borrow 1 meter from the 8m, resulting in 7m 100см - 43см.

Now, subtracting the centimeters, we have 100см - 43см = 57см.

Putting it all together, the result is 7m 57см.

Therefore, the calculations are:

4м 45см + 12м 56см = 16м 1см 10м - 2м 43см = 7м 57см
