the mass of Hinto's math book is 4,461 grams. what is the mass of 3 math books in kilograms? round your answer to the nearest thousandth

The total mass of 3 math book = 13.383 kilograms

Step-by-step explanation:

The mass of 1 math book = 4, 461 grams.

So, the mass of 3 math books = 3 x (mass of 1 math book)

= 3 x 4, 461 grams. = 13, 383 grams.

or, the mass of 3 math book = 13, 383 grams.

Now, 1000 grams = 1 kilogram

or, 1 gram = 1/1000 = 0.001 kilogram

So, 13, 383 grams = 13, 383 x (0.001 kilo grams)

= 13.383 kilograms

⇒ 13, 383 grams = 13.383 kilograms

hence, the mass of 3 math book = 13.383 kilograms

Also, rounding off the answer to the nearest thousandth, we get,

Hence, the total mass of 3 math book = 13.383 kilograms
