Question

10м-8м 8 дм +6м 9 дм

Answer 1

100дм-88дм+69дм=81дм=8м1дм

Answer 2

10 м -8 м 8дм+6 м 9дм=
10 м-8м 8дм=100-88=12 дм=1м 2 дм
1м+2дм+6м 9дм=8м 1 дм

Answer 3

To add the given lengths, let's convert them to a consistent unit, such as centimeters (cm).

First, let's convert the length "10 м" to centimeters: 1 meter (м) = 100 centimeters (см) So, 10 м = 10 * 100 = 1000 см

Next, let's convert the length "8 дм" to centimeters: 1 decimeter (дм) = 10 centimeters (см) So, 8 дм = 8 * 10 = 80 см

Similarly, let's convert the length "6 м" to centimeters: 6 м = 6 * 100 = 600 см

Finally, let's convert the length "9 дм" to centimeters: 9 дм = 9 * 10 = 90 см

Now, we can add the lengths in centimeters: 1000 см + 80 см + 600 см + 90 см = 1770 см

Therefore, the sum of the given lengths is 1770 centimeters (см).
