Question

Щенок тяжелее котёнка на 2 кг 400 г. найдите массу щенка если они весят 4 кг 600 г

Answer 1

1) Составим уравнение ,где Х это масса котёнка,тогда Х+2,4 это масса щенка
Х+(Х+2,4)=4,6
Х+Х+2,4=4,6
2Х=4,6-2,4
2Х=2,2
Х=2,2:2
Х=1,1кг ( весит котёнок)
2) 1,1кг+2,4кг=3,5кг( вес щенка).

Answer 2

Calculating the Puppy's Weight

To find the weight of the puppy, we can subtract the weight of the kitten from the combined weight of the puppy and the kitten.

The weight of the puppy and the kitten combined is 4 kg 600 g, and the kitten is 2 kg 400 g.

Step 1: Convert the weights to a common unit, grams.

Step 2: Subtract the weight of the kitten from the combined weight to find the weight of the puppy.

Let's calculate the weight of the puppy using these steps.

Step 1: Convert the Weights to Grams

The weight of the puppy and the kitten combined is 4 kg 600 g, and the weight of the kitten is 2 kg 400 g.

4 kg 600 g = (4 * 1000) g + 600 g = 4600 g 2 kg 400 g = (2 * 1000) g + 400 g = 2400 g

Step 2: Subtract the Weight of the Kitten from the Combined Weight

Weight of the puppy = Combined weight - Weight of the kitten Weight of the puppy = 4600 g - 2400 g = 2200 g

So, the weight of the puppy is 2200 grams.
