Question

На одну з вантажівок навантажили 7,9/20 т вантажу, а на іншу 2,3/20 т менше. Скільки вантажу на двох вантажівках разом? Дуже треба ваша допомога

Answer 1

На первую вантажівку навантажили 7,9/20 т вантажу.

На другу вантажівку навантажили на 2,3/20 т менше, тобто на (7,9/20 - 2,3/20) т = 5,6/20 т вантажу.

Разом на двох вантажівках навантажено:

7,9/20 т + 5,6/20 т = 13,5/20 т = 0,675 т

Ответ: На двох вантажівках разом навантажено 0,675 т вантажу.

I can help you with your question.

According to Google Translate, your question in English is:

Answer in detail. One truck was loaded with 7.9/20 tons of cargo, and the other with 2.3/20 tons less. How much cargo is on two trucks together? I really need your help.

To solve this problem, we can use the following steps:

- Let x be the amount of cargo on the second truck. Then, the amount of cargo on the first truck is x + 2.3/20. - The total amount of cargo on both trucks is x + (x + 2.3/20) = 2x + 2.3/20. - We know that the first truck was loaded with 7.9/20 tons of cargo, so we can write an equation: x + 2.3/20 = 7.9/20. - To solve for x, we can subtract 2.3/20 from both sides: x = 7.9/20 - 2.3/20 = 5.6/20. - Therefore, the amount of cargo on the second truck is 5.6/20 tons, and the amount of cargo on both trucks together is 2x + 2.3/20 = 2(5.6/20) + 2.3/20 = 13.5/20 tons.
