Question

30см+3дм4см 18мл-1см

Answer 1

Ответ:

1)64см; 2) 8мм

Пошаговое объяснение:

1)30см + 3дм4см= 30см + 30см(1дм=10см) +4см=64см;

2) 18мм-1см=18мм-10мм(1см=10мм)=8мм

Answer 2

To solve the given expressions, let's first convert all the measurements to the same unit for easier computation. We'll use centimeters (cm) as the common unit for both expressions.

1. 30 cm + 3 dm 4 cm: We need to convert the decimeters (dm) to centimeters (cm). Since 1 dm = 10 cm, we have: 3 dm * 10 cm/dm = 30 cm.

Now, we can add the measurements in centimeters: 30 cm + 30 cm + 4 cm = 64 cm.

So, 30 cm + 3 dm 4 cm = 64 cm.

2. 18 m - 1 cm: We need to convert meters (m) to centimeters (cm). Since 1 m = 100 cm, we have: 18 m * 100 cm/m = 1800 cm.

Now, we can subtract the measurement in centimeters: 1800 cm - 1 cm = 1799 cm.

So, 18 m - 1 cm = 1799 cm.

Final results:

• 30 cm + 3 dm 4 cm = 64 cm.
• 18 m - 1 cm = 1799 cm.
