please explain and show work.

300,000 - 60 = 299,940

299,940/300,000 = 0.9998 = 99.9% decrease

To calculate the percent decrease in the minutes of math worry this year, we need to find the difference between last year's and this year's minutes, and then divide that difference by the minutes last year. Finally, we multiply the result by 100 to find the percentage.

Last year's minutes of math worry: 300,000 minutes
This year's minutes of math worry: 60 minutes

The difference in minutes: 300,000 - 60 = 299,940 minutes

To find the percent decrease, we divide the difference in minutes by the minutes last year:

Percentage decrease = (299,940 / 300,000) * 100 = 99.98%

Therefore, you will experience a percent decrease of approximately 99.98% in the minutes of math worry this year compared to last year.
