Answer:
<u>7</u>5,575 - ten-thousands place; this 7 is worth 70,000
7<u>5</u>,575 - thousands place; this 5 is worth 5,000
75,<u>5</u>75 - hundreds place; this 5 is worth 500
75,5<u>7</u>5 - tens place; this 7 is worth 70
75,57<u>5</u> - ones place; this 5 is worth 5
Answer: 99% decrease
Step-by-step explanation: Since the number changes from 6,000 to 60, we know that it's decreasing. Now to find the percent decrease, we divide the amount of change by the original number.
The amount of change is the difference between 6,000 and 60 and the original number is 6,000.
6,000 - 60 is 5,940 so we are left with
and dividing 6,000 into 5,940 gives us 0<em>.</em>99.
Finally, since the problem is asking us for the <em>percent</em>, we write 0.999 as a percent by moving the decimal point 2 places to the right to get 99%.
So when a number changes from 6,000 to 60, it has decreased by 99%.
