Question

Решить двумя способами, даю 46 баллов: Купили 10 пакетиков семян редиски по 7 г в каждом пакетике. Сколько граммов семян осталось после того, как высеяли семена из 6 пакетиков?

Answer 1

(7*10)-(7*6)=70-42=28 г осталось              или 10-6=4 пак осталось     7*4=28 г семян осталось

Answer 2

10*7=70(это то сколько всего грамм семян в 10 пакетиках)
6*7=42(грамм в 6 пакетиках)
70-42=28(осталось граммов семян)

Answer 3

Calculation 1: Subtracting the weight of seeds from 6 packets

To find out how many grams of seeds are left after sowing the seeds from 6 packets, we need to subtract the weight of the seeds from these packets from the total weight of the seeds.

Given information: - Number of packets: 10 - Weight of seeds in each packet: 7 grams

To calculate the total weight of seeds in all packets, we multiply the number of packets by the weight of seeds in each packet: 10 packets * 7 grams/packet = 70 grams

Now, we need to find the weight of seeds left after sowing the seeds from 6 packets. To do this, we subtract the weight of seeds from 6 packets from the total weight of seeds: 70 grams - (6 packets * 7 grams/packet) = 70 grams - 42 grams = 28 grams

Therefore, there are 28 grams of seeds left after sowing the seeds from 6 packets.

Calculation 2: Subtracting the weight of seeds from 4 packets

Alternatively, we can calculate the weight of seeds left by subtracting the weight of seeds from 4 packets from the total weight of seeds.

Given information: - Number of packets: 10 - Weight of seeds in each packet: 7 grams

To calculate the total weight of seeds in all packets, we multiply the number of packets by the weight of seeds in each packet: 10 packets * 7 grams/packet = 70 grams

Now, we need to find the weight of seeds left after sowing the seeds from 6 packets. To do this, we subtract the weight of seeds from 4 packets from the total weight of seeds: 70 grams - (4 packets * 7 grams/packet) = 70 grams - 28 grams = 42 grams

Therefore, there are 42 grams of seeds left after sowing the seeds from 6 packets.
