Express 4 kg and 20 g in kg.

Answer»

Answer: 4.02 kg

Step-by-step explanation:

We are told to express 4 kg and 20 G in kg.

To solve such similar types of problems you should know that 1 kg = 1000 g.

Now lets get into the problem.

Here you get two choices, Either convert 20 g into kg or convert 4 kg into g.

I would Like to convert 4 kg into g since it would be EASY and we don't have to PLAY with decimals at this moment.

So we know that:

1 kg = 1000 g

4 kg = x

Lets cross multiply, and we get

4*1000 = x

4000 = x

Therefore 4 kg in g would be 4000 g.

Now We GOT 4000 g and 20 g, Both have same units, add it up.

4000 + 20 = 4020 g

Now we have to convert this 4020 in kg.

To convert g into kg we simply divide the given number by 1000

So 4 kg and 20 g in kg would be

4020/1000 = 4.02 kg
