Question

QON ORCHEOLO Из 200 кг подсолнечника получается 100 кг масла. Сколь- ко надо килограммов подсолнечника, чтобы получить 9т масла? Реши задачу двумя способами. Не​

Answer 1

Ответ:

способ.

1) 200 : 100 = 2 (раза) больше подсолнечника надо, чтобы получить масло

2) 9 т * 2 = 18 т = 18000(кг) подсолнечника надо, чтобы получить 9 т масла

2 способ.

1) 9 т = 9000 кг

9000 : 100 = 90 (раз) больше масла в 9 т , чем в 100 кг.

2) 200 * 90 = 18000 (кг ) подсолнечника надо, чтобы получить 9 т масла

Answer 2

To find out how many kilograms of sunflower seeds are needed to produce 9 tons of oil, we can solve the problem using two different methods.

Method 1: Using Proportions

We can set up a proportion to solve the problem. Let's assume that x represents the number of kilograms of sunflower seeds needed to produce 9 tons (9000 kilograms) of oil. The proportion can be set up as follows:

200 kg / 100 kg = x kg / 9000 kg

To solve for x, we can cross-multiply and then divide:

200 kg * 9000 kg = 100 kg * x kg

x kg = (200 kg * 9000 kg) / 100 kg

Calculating this expression gives us:

x kg = 1800000 kg / 100 kg = 18000 kg

Therefore, 18,000 kilograms of sunflower seeds are needed to produce 9 tons of oil.

Method 2: Using Ratios

Another way to solve the problem is by using ratios. We know that 200 kilograms of sunflower seeds produce 100 kilograms of oil. We can set up a ratio to find out how many kilograms of sunflower seeds are needed to produce 9 tons of oil:

200 kg : 100 kg = x kg : 9000 kg

To solve for x, we can cross-multiply and then divide:

200 kg * 9000 kg = 100 kg * x kg

x kg = (200 kg * 9000 kg) / 100 kg

Calculating this expression gives us:

x kg = 1800000 kg / 100 kg = 18000 kg

Therefore, using both methods, we find that 18,000 kilograms of sunflower seeds are needed to produce 9 tons of oil.
