Answer 1

Старший брат-44кг 700г
малышка-14кг 900г
35800-14900=20кг 900г

Answer 2

Calculating the Weight Difference

To calculate how much lighter the youngest sister is compared to Masha, we can follow these steps:

1. Convert Masha's weight to grams. 2. Convert the older brother's weight to grams. 3. Calculate the weight of the youngest sister. 4. Find the difference in weight between the youngest sister and Masha.

Step 1: Convert Masha's Weight to Grams

Masha's weight is 35 kg 800 g. To convert this to grams: - 35 kg = 35,000 g - 35,000 g + 800 g = 35,800 g

Masha's weight in grams: 35,800 g

Step 2: Convert the Older Brother's Weight to Grams

The older brother is 8 kg 900 g heavier than Masha. To convert this to grams: - 8 kg = 8,000 g - 8,000 g + 900 g = 8,900 g

The older brother's weight in grams: 8,900 g

Step 3: Calculate the Weight of the Youngest Sister

The youngest sister weighs one-third of the older brother's weight.

The youngest sister's weight = (1/3) * (older brother's weight)

Step 4: Find the Difference in Weight

To find out how much lighter the youngest sister is compared to Masha, we can subtract Masha's weight from the youngest sister's weight.

Let's calculate the weight of the youngest sister and the difference in weight.

I will now perform the calculations.
