Question

45дм + 3м 3см=3м 5дм 9см-1м 4дм 4см=

Answer 1

45дм + 3м 3см= 450см + 303см= 753см = 7м 5дм 3см
3 м 5дм 9см - 1м 4дм 4см= 359см-144см= 215см= 2м 1дм 5см

Answer 2

To solve this arithmetic problem, let's break it down step by step:

Step 1: Addition 45 dm + 3 m 3 cm

First, convert dm to cm: 45 dm = 45 * 10 cm = 450 cm

Now, we can add the lengths: 450 cm + 3 m 3 cm

Convert 3 m to cm: 3 m = 3 * 100 cm = 300 cm

Adding the lengths in cm: 450 cm + 300 cm + 3 cm = 753 cm

Step 2: Subtraction 3 m 5 dm 9 cm - 1 m 4 dm 4 cm

Convert the lengths to cm: 3 m 5 dm 9 cm = 3 * 100 cm + 5 * 10 cm + 9 cm = 300 cm + 50 cm + 9 cm = 359 cm

1 m 4 dm 4 cm = 1 * 100 cm + 4 * 10 cm + 4 cm = 100 cm + 40 cm + 4 cm = 144 cm

Now, subtract the lengths in cm: 359 cm - 144 cm = 215 cm

Step 3: Final result We have the result from Step 1 as 753 cm and the result from Step 2 as 215 cm.

To express the final result in meters, decimeters, and centimeters, we need to perform conversions:

753 cm = 7 m 5 dm 3 cm (since 1 m = 10 dm = 100 cm)

215 cm = 2 m 1 dm 5 cm

Therefore, the final result is: 7 m 5 dm 3 cm - 2 m 1 dm 5 cm = 5 m 4 dm 10 cm.
