The prefix ‘kilo-‘ means a thousand.

So a kilo-gram Is a thousand grams .
1 kilogram = 1,000 grams
How many kilograms is 970 grams?
Round your answer to the nearest tenth of a kilogram.

Answer 1

0.97 kg, 1.0kg

Step-by-step explanation:

As you have mentioned in the question, to convert kilo-gram to grams, this conversion is used, 1 kilogram = 1,000 grams

Initially, when one has to convert from one unit to another, there is a lot of confusion. To avoid any such, multiply and divide the number with units to which it has to be converted.

Here,

970 g =
`970 g *(1 kg)/(1 kg)`

This makes no difference to the number.

970 g =
`970 g *(1 kg)/(1000 g)`

As, 1 kg= 1,000 g

970 g =
`(970)/(1000) kg`

970 g = 0.97 kg

Rounding this off to the nearest tenth of a kilogram.

The tenths place is immediately to the right of the decimal point.

Here, 9 is at the tenth's place. Round the tenth's place up if the digit at hundredth's place is greater than or equal to 5. Since, 7 > 5, up the number at tenth's place.

So, answer is 1.0 kg
