Calculation of Percentages

To calculate the percentages of seeds and fiber from the mass of raw cotton, we need to use the given information:

- One ton of raw cotton yields 350 kg of fiber and 500 kg of seeds.

To find the percentage of seeds and fiber from the mass of raw cotton, we can use the following formulas:

Percentage of seeds = (Mass of seeds / Mass of raw cotton) * 100

Percentage of fiber = (Mass of fiber / Mass of raw cotton) * 100

Let's calculate these percentages:

Percentage of seeds:

The mass of seeds is given as 500 kg, and the mass of raw cotton is 1000 kg (1 ton). Plugging these values into the formula:

Percentage of seeds = (500 kg / 1000 kg) * 100 = 50%

Therefore, the seeds make up 50% of the mass of raw cotton.

Percentage of fiber:

The mass of fiber is given as 350 kg. Plugging this value into the formula:

Percentage of fiber = (350 kg / 1000 kg) * 100 = 35%

Therefore, the fiber makes up 35% of the mass of raw cotton.

Relationship between Seed Mass and Fiber Mass

To find the percentage of fiber from the mass of seeds, we can use the following formula:

Percentage of fiber from seed mass = (Mass of fiber / Mass of seeds) * 100

Let's calculate this percentage:

The mass of fiber is given as 350 kg, and the mass of seeds is given as 500 kg. Plugging these values into the formula:

Percentage of fiber from seed mass = (350 kg / 500 kg) * 100 = 70%

Therefore, the mass of fiber is 70% of the mass of seeds.

In summary:

- The seeds make up 50% of the mass of raw cotton. - The fiber makes up 35% of the mass of raw cotton. - The mass of fiber is 70% of the mass of seeds.
