The equation to solve this is 0.001(4,458x4). The answer is 17.832

Answer:

The weight of 4 math books is 17.832 kilograms.

Step-by-step explanation:

Given:

weight of math books = 4458 grams

number of math books = 4


1 kg = 1000 grams


4458 grams * 1kg/1000 grams = 4458 kg/1000 = 4.458 kg

4.458 kg * 4 books = 17.832 kg


OR


4458 grams * 4 books = 17832 grams

17832 grams * 1kg/1000 grams = 17832 kg/1000 = 17.832 kg
