Question

C)56m - 56dm= d)45cm+45mm=

Answer 1

Ответ:

1) 56 m - 56dm = 504 dm = 50 m 4 dm

2) 45cm + 45 mm = 505 mm=50 cm 5 mm

Answer 2

c) To subtract 56dm from 56m, we need to convert either meters or decimeters to a common unit. Let's convert 56m to decimeters:

56m = 56 x 10 dm/m = 560 dm

Now we can subtract 56dm from 560dm:

560dm - 56dm = 504dm

Therefore, 56m - 56dm = 504dm.

d) To add 45cm and 45mm, we need to convert one of the units to match the other. Let's convert 45mm to centimeters:

1cm = 10mm

So, 45mm = 45/10 cm = 4.5 cm

Now we can add 45cm and 4.5cm:

45cm + 4.5cm = 49.5cm

Therefore, 45cm + 45mm = 49.5cm.
