Question

В первый день в магазине продали 1/3 овощей ,а во второй день -2/9 .После этого в магазине осталось 5 (целых)3/5 т овощей.Сколько тонн овощей было в магазине первоначально?

Answer 1

1) 1/3 + 2/9 = (3+2) /9 = 5/9 (части ) овощей продали в 1 и во 2 день всего
2) 1 - 5/9 = 4/9 (части) осталось в магазине.
3) 4/9 части составляют 5 3/5 т.    5 3/5 т = 5600кг;  4/9 части = 5600кг
     5600 : 4/9 = 12600(кг) = 12т 600кг
Ответ: 12т 600кг было в магазине первоначально.

Answer 2

Х - було
х=1/3х+2/9х+5ц3/5
х-5/9х=5ц3/5
4/9х=28/5
х=28/5:4/9=28/5*9/4=36/5=5ц1/5

Calculation of the Initial Quantity of Vegetables in the Store

To calculate the initial quantity of vegetables in the store, we can use the information provided about the sales on the first and second days, as well as the remaining quantity of vegetables.

Let's denote the initial quantity of vegetables in the store as x.

On the first day, 1/3 of the vegetables were sold, which means 2/3 of the vegetables remained in the store.

On the second day, 2/9 of the remaining vegetables were sold, which means 7/9 of the vegetables remained in the store.

According to the information given, 5 3/5 tons of vegetables remained in the store after the second day.

We can set up the following equation to solve for x:

(7/9) * (2/3) * x = 5 3/5

To solve this equation, we can follow these steps:

Step 1: Convert the mixed fraction 5 3/5 to an improper fraction. - 5 3/5 is equivalent to 28/5.

Step 2: Multiply both sides of the equation by the reciprocal of (7/9) * (2/3), which is (3/2) * (9/7). - This simplifies the equation to: x = (5 3/5) * (3/2) * (9/7).

Step 3: Perform the multiplication and simplify the fraction. - (5 3/5) * (3/2) * (9/7) = (28/5) * (3/2) * (9/7) = 36.

Therefore, the initial quantity of vegetables in the store was 36 tons.
