Question

20дм9см:11= 5кг350г:25=

Answer 1

$20$ дм $9$ см $: 11$ = $209$ см $:11$ = $19$ см

1 дм = 10 см

20 дм = 200 см

$5$ кг $350$ г $:25$ = $5350$ г $:25$ = $214$ г

1 кг = 1000 г

5 кг = 5000 г

Answer 2

To solve the given equations, let's convert the units to a common base.

20 dm 9 cm can be converted to centimeters (cm) by multiplying by 10:

20 dm 9 cm = (20 * 10) cm + 9 cm = 200 cm + 9 cm = 209 cm

Now, let's solve the first equation:

209 cm ÷ 11 = 19 cm

So, 20 dm 9 cm is equal to 19 cm.

Next, let's solve the second equation:

5 kg 350 g can be converted to grams (g) by multiplying by 1000:

5 kg 350 g = (5 * 1000) g + 350 g = 5000 g + 350 g = 5350 g

Now, let's solve the second equation:

5350 g ÷ 25 = 214 g

So, 5 kg 350 g is equal to 214 g.
