Answer 1

1)135:9=15(кг)-печенья в одной коробке

2)7х15=105(кг)-в семи коробках

3)135-105=30(кг) меньше

Ответ:на 30кг меньше привезли в другой магазин

Answer 2

1)135:9=15 кг печенья в 1 коробке

2)7*15=105 кг печенья привезли в другой магазин

3)135-105=30 кг 

ответ: на 30 кг печенья меньше привезли во второй магазин

Answer 3

Calculation of the Difference in Weight of Cookies

To calculate the difference in weight of cookies between the two stores, we need to subtract the weight of cookies in the second store from the weight of cookies in the first store.

The weight of cookies in the first store is given as 135 kg, and they were delivered in 9 boxes. The weight of cookies in the second store is not provided, but we know that they were delivered in 7 boxes.

Let's assume that the weight of cookies in the second store is x kg.

Therefore, the equation to calculate the weight difference is:

135 kg - x kg = weight difference

To find the value of x, we can rearrange the equation:

x kg = 135 kg - weight difference

Now, we need to find the weight difference. Let's proceed with the calculation.

Calculation:

Weight of cookies in the first store = 135 kg Weight of cookies in the second store = x kg

Weight of cookies in the first store = 9 boxes Weight of cookies in the second store = 7 boxes

To find the weight difference, we can set up a proportion:

9 boxes / 135 kg = 7 boxes / x kg

Cross-multiplying the proportion:

9 * x kg = 7 * 135 kg

Simplifying the equation:

9x = 7 * 135

Dividing both sides by 9:

x = (7 * 135) / 9

Calculating the value of x:

x = 7 * 15 = 105 kg

Therefore, the weight of cookies in the second store is 105 kg.

Answer:

The weight of cookies in the second store is 105 kg less than the weight of cookies in the first store.
