Answer 1

Просто ищем тетрадь в клетку, смотрим заднюю обложку, и вуаля! Все меры у вас перед глазами. Потом просто большее переводим в меньшее, согласно таблице. 1) 5 суток=5*24ч=120 часов. 120 - 18= 102 ч.=4 суток 6 часов.
2) 2 часа=2*60мин=120мин. 120мин-35мин=85мин.= 1 час 25 мин.
3) 9 мин=9*60с=540с. 540с-24с= 516с.= 8 мин.36с.
4)5 кв. см=5*100кв.мм.=500кв.мм. 500 кв.мм.-40кв.мм=460кв.мм.=4 кв.см.60кв.мм.
5) 6 кв.м=6*100кв.дм=600кв.дм. 600кв.дм-38кв.дм=562кв.дм.=5кв.м.62кв.дм.
6) 9 кв.м=9*100кв.дм=900кв.дм. 900кв.дм-15кв.дм=885кв.дм.=8кв.м.85кв.дм.
7) 6а=6*100кв.м=600кв.м. 600кв.м-50кв.м=550кв.м.=5а 50кв.м.
8) 8га=8*100а.=800а. 800а-21а=779а.=7га.79а.
9) У вас все правильно написано в 9? Из кв. мм не вычесть га.

Answer 2

1) 5 суток - 18 часов

To calculate the result of subtracting 18 hours from 5 days, we need to convert both values to a common unit of time. Let's convert 5 days to hours first.

1 day = 24 hours, so 5 days would be equal to 5 * 24 = 120 hours.

Now we can subtract 18 hours from 120 hours:

120 hours - 18 hours = 102 hours.

Therefore, the result of subtracting 18 hours from 5 days is 102 hours.

2) 2 часа - 35 минут

To subtract 35 minutes from 2 hours, we need to convert both values to a common unit of time. Let's convert 2 hours to minutes first.

1 hour = 60 minutes, so 2 hours would be equal to 2 * 60 = 120 minutes.

Now we can subtract 35 minutes from 120 minutes:

120 minutes - 35 minutes = 85 minutes.

Therefore, the result of subtracting 35 minutes from 2 hours is 85 minutes.

3) 9 минут - 24 секунды

To subtract 24 seconds from 9 minutes, we need to convert both values to a common unit of time. Let's convert 9 minutes to seconds first.

1 minute = 60 seconds, so 9 minutes would be equal to 9 * 60 = 540 seconds.

Now we can subtract 24 seconds from 540 seconds:

540 seconds - 24 seconds = 516 seconds.

Therefore, the result of subtracting 24 seconds from 9 minutes is 516 seconds.

4) 5 кв. см - 40 кв. мм

To subtract 40 square millimeters from 5 square centimeters, we need to convert both values to a common unit of area.

1 square centimeter (cm^2) = 100 square millimeters (mm^2).

So, 5 square centimeters would be equal to 5 * 100 = 500 square millimeters.

Now we can subtract 40 square millimeters from 500 square millimeters:

500 square millimeters - 40 square millimeters = 460 square millimeters.

Therefore, the result of subtracting 40 square millimeters from 5 square centimeters is 460 square millimeters.

5) 6 кв. м - 38 кв. дм

To subtract 38 square decimeters from 6 square meters, we need to convert both values to a common unit of area.

1 square meter (m^2) = 100 square decimeters (dm^2).

So, 6 square meters would be equal to 6 * 100 = 600 square decimeters.

Now we can subtract 38 square decimeters from 600 square decimeters:

600 square decimeters - 38 square decimeters = 562 square decimeters.

Therefore, the result of subtracting 38 square decimeters from 6 square meters is 562 square decimeters.

6) 9 кв. м - 15 кв. дм

To subtract 15 square decimeters from 9 square meters, we need to convert both values to a common unit of area.

1 square meter (m^2) = 100 square decimeters (dm^2).

So, 9 square meters would be equal to 9 * 100 = 900 square decimeters.

Now we can subtract 15 square decimeters from 900 square decimeters:

900 square decimeters - 15 square decimeters = 885 square decimeters.

Therefore, the result of subtracting 15 square decimeters from 9 square meters is 885 square decimeters.

7) 6 а - 50 кв. м

It seems there might be a typo in the question. The unit "а" is not a commonly used unit of measurement. Could you please provide more information or clarify the unit you are referring to?

8) 8 га - 21 а

To subtract 21 acres from 8 hectares, we need to convert both values to a common unit of area.

1 hectare (ha) = 2.47105 acres.

So, 8 hectares would be equal to 8 * 2.47105 = 19.7684 acres (rounded to 4 decimal places).

Now we can subtract 21 acres from 19.7684 acres:

19.7684 acres - 21 acres = -1.2316 acres (rounded to 4 decimal places).

Therefore, the result of subtracting 21 acres from 8 hectares is approximately -1.2316 acres.

9) 4 кв. мм - 90 га

To subtract 90 hectares from 4 square millimeters, we need to convert both values to a common unit of area.

1 hectare (ha) = 10,000,000 square millimeters (mm^2).

So, 90 hectares would be equal to 90 * 10,000,000 = 900,000,000 square millimeters.

Now we can subtract 900,000,000 square millimeters from 4 square millimeters:

4 square millimeters - 900,000,000 square millimeters = -899,999,996 square millimeters.

Therefore, the result of subtracting 90 hectares from 4 square millimeters is approximately -899,999,996 square millimeters.

I hope this helps! Let me know if you have any further questions.
