Question

3дм4см+6дм6см= 1м0дм0см-3дм4см= 3дм5см+4дм+5см=

Answer 1

Нужно знать: 1 дм = 10 см, 1 м = 10 дм = 100 см

3 дм 4 см + 6 дм 6 см = 9 дм 10 см = 10 дм

1 м 0 дм 0 см - 3 дм 4 см = 10 дм 0 см - 3 дм 4 см = 9 дм 10 см - 3 дм 4 см =

= 6 дм 6 см

3 дм 5 см + 4 дм + 5 см = 3 дм 5 см + 4 дм 5 см = 7 дм 10 см = 8 дм

Answer 2

Let's solve each of these equations step by step:

1. $3\text{дм}4\text{см} + 6\text{дм}6\text{см}$ To add these two measurements together, we can first add the centimeters and then the decimeters separately:

$4\text{см} + 6\text{см} = 10\text{см}$

Now, let's add the decimeters:

$3\text{дм} + 6\text{дм} = 9\text{дм}$

So, $3\text{дм}4\text{см} + 6\text{дм}6\text{см} = 9\text{дм}10\text{см}.$

2. $1\text{м}0\text{дм}0\text{см} - 3\text{дм}4\text{см}$ To subtract these measurements, we again subtract the centimeters and decimeters separately:

$0\text{см} - 4\text{см} = -4\text{см}$

Now, let's subtract the decimeters:

$10\text{дм} - 3\text{дм} = 7\text{дм}$

So, $1\text{м}0\text{дм}0\text{см} - 3\text{дм}4\text{см} = 7\text{дм}-4\text{см} = 6\text{дм}6\text{см}.$

3. $3\text{дм}5\text{см} + 4\text{дм} + 5\text{см}$ To add these measurements together, we can first add the centimeters and then the decimeters separately:

$5\text{см} + 5\text{см} = 10\text{см}$

Now, let's add the decimeters:

$3\text{дм} + 4\text{дм} = 7\text{дм}$

So, $3\text{дм}5\text{см} + 4\text{дм} + 5\text{см} = 7\text{дм}10\text{см}.$

Now, we have the results for each equation:

1. $3\text{дм}4\text{см} + 6\text{дм}6\text{см} = 9\text{дм}10\text{см}$
2. $1\text{м}0\text{дм}0\text{см} - 3\text{дм}4\text{см} = 6\text{дм}6\text{см}$
3. $3\text{дм}5\text{см} + 4\text{дм} + 5\text{см} = 7\text{дм}10\text{см}$
