Answer 1

90 газет продали и 180 журналов 
Меньше продано газет 
В 2 раза

600/100*15=90 газет продали
200/100*2=180 журналов продали
180/90=2

Answer 2

600*0.15=90 газет
200*0.9=180 журналов
180/90=2 раза
Ответ в 2 раза продано меньше газет чем журналов

Answer 3

Calculation of the Number of Newspapers and Magazines Sold

To determine whether more newspapers or magazines were sold, we need to calculate the number of newspapers and magazines sold before noon.

Given: - Number of newspapers brought to the kiosk: 600 - Number of magazines brought to the kiosk: 200 - Percentage of newspapers sold before noon: 15% - Percentage of magazines sold before noon: 90%

To calculate the number of newspapers sold, we multiply the total number of newspapers by the percentage sold: 600 newspapers * 15% = 90 newspapers.

To calculate the number of magazines sold, we multiply the total number of magazines by the percentage sold: 200 magazines * 90% = 180 magazines.

Therefore, fewer newspapers were sold compared to magazines, with a difference of 90 newspapers - 180 magazines = 90.

Conclusion

In conclusion, fewer newspapers were sold compared to magazines. The number of newspapers sold was 90, while the number of magazines sold was 180.
