Question

В двух мешках 140 кг муки, 2/7 из которых в первом мешке. Сколько муки во втором мешке?

Answer 1

1)140:7*2=40(кг)-в 1 мешке
2)140-40=100(кг)
Ответ:во втором мешке 100 кг муки.

Answer 2

Solution:

To find out how much flour is in the second bag, we can use the information provided about the total amount of flour and the proportion in the first bag.

Let's denote the total amount of flour as F and the amount of flour in the first bag as 2/7F. We know that the total amount of flour in both bags is 140 kg. Therefore, we can set up the equation:

2/7F + x = 140

Where x represents the amount of flour in the second bag.

Calculation:

Using the given information, we can solve for x:

2/7F + x = 140

Given that the total amount of flour is 140 kg, we can substitute this value for F:

2/7*140 + x = 140

40 + x = 140

Subtracting 40 from both sides:

x = 140 - 40

x = 100

Answer:

So, the amount of flour in the second bag is 100 kg.
