Вес Ани - 36200 граммов - 36,2 кг, так как в одном килограмме 1000 грамм - верно.
Рост Ани - 0,00154 км - 154 сантиметра, так как в одном километре 100000 сантиметров - верно.

Answer 2

Determining the Error in Weight and Height Measurements

Anya stated that her weight is 36200 grams and her height is 0.00154 kilometers, while Ira stated that her weight is 0.0037 tons and her height is 1490 millimeters. Let's analyze these measurements to determine who made an error.

Anya's Measurements: - Weight: 36200 grams - Height: 0.00154 kilometers

Ira's Measurements: - Weight: 0.0037 tons - Height: 1490 millimeters

Converting Measurements for Analysis

First, let's convert the measurements to a consistent unit for comparison.

Converting Anya's Measurements: - Weight: 36200 grams = 36.2 kilograms (1 gram = 0.001 kilograms) - Height: 0.00154 kilometers = 1.54 meters (1 kilometer = 1000 meters)

Converting Ira's Measurements: - Weight: 0.0037 tons = 3.7 kilograms (1 ton = 1000 kilograms) - Height: 1490 millimeters = 1.49 meters (1 meter = 1000 millimeters)

Analysis of Measurements

Now that the measurements are in the same units, we can compare them directly.

Anya's Measurements: - Weight: 36.2 kilograms - Height: 1.54 meters

Ira's Measurements: - Weight: 3.7 kilograms - Height: 1.49 meters

Identifying the Error

Upon analysis, it is evident that Ira made an error in her weight and height measurements. Her weight of 3.7 kilograms and height of 1.49 meters are more realistic and consistent with typical human measurements, while Anya's measurements also align with expected human weight and height ranges.

Therefore, based on the provided measurements, Ira's statements about her weight and height appear to be inaccurate.
