Calculation of Yarn from Unraveling Socks

To calculate the amount of yarn obtained from unraveling the socks, we can use the given information that the grandmother unraveled 7/8 of the old socks and obtained 280 grams of yarn.

Step 1: Calculate the Yarn from 1 Pair of Socks First, we need to find out how much yarn is obtained from one pair of socks. Since the grandmother unraveled 7/8 of the old socks, the remaining 1/8 represents one pair of socks.

Step 2: Calculate the Total Yarn Next, we can calculate the total amount of yarn obtained by multiplying the yarn from one pair of socks by the total number of pairs of socks.

Let's proceed with the calculations.

Calculation

1. Yarn from 1 Pair of Socks: - 7/8 of the socks = 280 grams - 1/8 of the socks = 280 grams / 7 = 40 grams

2. Total Yarn from All Socks: - Total pairs of socks = 7/8 + 1/8 = 1 - Total yarn = Yarn from 1 pair of socks * Total pairs of socks = 40 grams * 8 = 320 grams

Therefore, if the grandmother unravels all the old socks, she will obtain 320 grams of yarn.
