Question

1)3км 885 см + 7км 728м = 2)6кг 150г умножить 28=

Answer 1

1) 1 м = 100 см

885 см = 800 см + 85 см = 8 м 85 см

3 км 885 см + 7 км 728 м = (3 + 7) км + (8 + 728) м + 85 см =

= 10 км 736 м 85 см;

- - - - - - - - - - - - - - - - - - - -

2) 1 кг = 1000 г

6 150 г · 28  = 172 200 г = 172 кг 200 г.

Answer 2

1) = 10км 736м 85см
2) = 172кг 200г

Answer 3

1. To add 3km 885cm and 7km 728m, we first need to convert all units to the same base unit. Let's choose meters as our base unit.

3km 885cm = (3 x 1000) + 885 = 3885 meters 7km 728m = (7 x 1000) + 728 = 7728 meters

Now, we can add them:

3885 + 7728 = 11613 meters

Therefore, 3km 885cm + 7km 728m = 11km 613m.

2. To multiply 6kg 150g by 28, we can ignore the units for now and just multiply the numerical values:

6.150 x 28 = 172.2

Now, we need to convert back to kilograms and grams. There are 1000 grams in a kilogram, so we can divide our result by 1000 to get the kilograms:

172.2 ÷ 1000 = 0.1722 kg

We can find the remaining grams by multiplying the decimal part by 1000:

0.1722 x 1000 = 172.2 g

Therefore, 6kg 150g multiplied by 28 is equal to 4kg 576g (rounded to the nearest gram).
