Answer 1

9м 7см - 5м= 4м 7см
9дм + 4м 8см=4м 98см или 4м 9дм 8см

Answer 2

Calculation:

To calculate the given expression: 9m 7cm - 5m 9dm + 4m 8cm 10dm + 3m 18cm - 2m 99cm, we can perform the following steps:

1. Convert all measurements to a consistent unit (centimeters). 2. Perform the arithmetic operations.

Let's proceed with the calculation.

Conversion to Centimeters:

- 9m = 900cm - 7cm = 7cm - 5m = 500cm - 9dm = 90cm - 4m = 400cm - 8cm = 8cm - 10dm = 100cm - 3m = 300cm - 18cm = 18cm - 2m = 200cm - 99cm = 99cm

Arithmetic Operations:

- (900cm + 7cm) - (500cm + 90cm) + (400cm + 8cm + 100cm) + (300cm + 18cm) - (200cm + 99cm) - 907cm - 590cm + 508cm + 318cm - 299cm - 844cm

The result of the calculation is 844cm.
