Question

Масса чашки 140 г,а масса блюдца 180 г.Купили 12 чашек с блюдцами.Сколько весит эта покупка?На сколько купленные чашки легче купленных блюдец? Пожалуйста скажите ответ!!!!!

Answer 1

1) 140 * 12 = 1680 (г) - весят 12 чашек
2) 180 *12 = 2160 (г) - весят 12 блюдец
3) 11680 + 2160 = 3840 г = 3 кг 840 г - весят 12 чашек и 12 блюдец
4) 2160 - 1680 = 480 (г) - на столько чашки легче блюдец

Answer 2

1)(140+180)*12=3840(Г)-Весят 12 чашек с блюдцами
2)(180*12):(140*12)=2160-1680=480(г)-чашки легче блюдец
Ответ:3840;на 480

Answer 3

Calculating the Total Weight of the Purchase

To calculate the total weight of the purchase, we can use the given masses of the cup and saucer.

The mass of the cup is 140 g and the mass of the saucer is 180 g.

To find the total weight of 12 cups with saucers, we can use the following formula:

Total weight = (Mass of cup + Mass of saucer) * Number of cups

Substituting the given values: Total weight = (140 g + 180 g) * 12

Calculating: Total weight = 320 g * 12 Total weight = 3840 g

So, the total weight of the purchase is 3840 grams.

Comparing the Weight Difference between Cups and Saucers

To find out how much lighter the cups are compared to the saucers, we can calculate the weight difference between the cups and saucers.

The weight difference is given by: Weight difference = Mass of saucer - Mass of cup

Substituting the given values: Weight difference = 180 g - 140 g Weight difference = 40 g

So, the cups are 40 grams lighter than the saucers.

Therefore, the total weight of the purchase is 3840 grams, and the cups are 40 grams lighter than the saucers.
