Calculation of Sasha's weight

To find out Sasha's weight, we can use the information given in the question. Let's break it down step by step:

1. The total weight of Dasha, Pasha, and Sasha together is 120 kilograms. 2. Dasha weighs 40 kilograms. 3. Pasha weighs 7/8 of Dasha's weight.

To calculate Sasha's weight, we can subtract the combined weight of Dasha and Pasha from the total weight:

Total weight - (Dasha's weight + Pasha's weight) = Sasha's weight

Let's calculate it:

Total weight = 120 kilograms Dasha's weight = 40 kilograms Pasha's weight = 7/8 * Dasha's weight

Now we can substitute the values and calculate Sasha's weight:

Sasha's weight = Total weight - (Dasha's weight + Pasha's weight) Sasha's weight = 120 kilograms - (40 kilograms + (7/8 * 40 kilograms))

To simplify the calculation, let's convert 7/8 to a decimal:

7/8 = 0.875

Now we can substitute the values and calculate Sasha's weight:

Sasha's weight = 120 kilograms - (40 kilograms + (0.875 * 40 kilograms)) Sasha's weight = 120 kilograms - (40 kilograms + 35 kilograms) Sasha's weight = 120 kilograms - 75 kilograms Sasha's weight = 45 kilograms

Therefore, Sasha weighs 45 kilograms.
