Calculation of Weight Differences

To calculate the weight difference between the youngest sister and Masha, we need to consider the weights of Masha, the older brother, and the youngest sister.

Masha weighs 35 kg 800 g, and the older brother is 8 kg 900 g heavier than Masha. The youngest sister weighs one-third of the older brother's weight.

Let's break down the calculations step by step:

1. Masha's weight: 35 kg 800 g. 2. Older brother's weight: Masha's weight + 8 kg 900 g. 3. Youngest sister's weight: One-third of the older brother's weight.

Calculation Steps

1. Convert Masha's weight to grams: 35 kg 800 g = 35,800 g. 2. Convert the older brother's weight to grams: Masha's weight + 8 kg 900 g = 35,800 g + 8,900 g = 44,700 g. 3. Calculate the youngest sister's weight: One-third of the older brother's weight = 44,700 g / 3.

Calculation Results

1. Masha's weight: 35,800 g. 2. Older brother's weight: 44,700 g. 3. Youngest sister's weight: 44,700 g / 3.

Now, let's calculate the weight difference between the youngest sister and Masha.

Weight Difference Calculation

To find the weight difference, we subtract Masha's weight from the youngest sister's weight.

1. Youngest sister's weight: 44,700 g / 3. 2. Weight difference: Youngest sister's weight - Masha's weight.

Weight Difference Calculation Result

To determine the weight difference, we subtract Masha's weight from the youngest sister's weight.

Weight difference = Youngest sister's weight - Masha's weight.

Please note that we need the exact weight of the youngest sister to calculate the weight difference accurately.
