The bunny weighs 405 grams over the summer, its mass increases 9 times, how much a rabbit weighs if, together with the bunny, she weighs 9 kg.
1) Determine the mass of the rabbit.
To do this, multiply its initial weight by the indicated difference, namely 9.
405 * 9 = 3645 grams.
2) We convert the mass of the rabbit from grams to kilograms.
Since 1 kg – 1000 grams, we get:
3645/1000 = 3.645 kg.
3) Find the mass of the rabbit.
To do this, we subtract the mass of the rabbit from the total weight of the rabbit and the bunny.
9 – 3.645 = 5.355 kg.
5.355 kg = 5 kg 355 grams.
The rabbit weighs 5 kg 355 g.
