Answer 2

Problem Analysis

We are given that a grandmother bought 200g of white wool and 600g of blue wool. The total number of identical balls of wool is eight. We need to find the mass of one ball of wool and determine how many balls of white wool the grandmother bought and how many series she bought.

Solution

Let's assume the mass of one ball of wool is x grams.

The total mass of the white wool is 200g, and the total mass of the blue wool is 600g. Since there are eight identical balls of wool in total, we can set up the following equation:

8x = 200 + 600

Simplifying the equation, we have:

8x = 800

Dividing both sides of the equation by 8, we find:

x = 100

Therefore, the mass of one ball of wool is 100 grams.

To find out how many balls of white wool the grandmother bought, we divide the total mass of the white wool (200g) by the mass of one ball (100g):

Number of balls of white wool = 200g / 100g = 2

So, the grandmother bought 2 balls of white wool.

To determine the number of series, we divide the total number of balls (8) by the number of balls of white wool (2):

Number of series = 8 balls / 2 balls = 4

Therefore, the grandmother bought 4 series of wool.

Answer

The mass of one ball of wool is 100 grams. The grandmother bought 2 balls of white wool and 4 series of wool.
