Answer:
80, 0.9, 8, 0.09
Explanation:
Places are...
1 - ones
10 - tens
100 - hundreds
etc.
Decimal places are...
0.0 - tenths
0.00 - hundredths
0.000 - thousandths
etc.
(a) The digit in the ones place is 8. It is 1/10 of 80 because...
1/10 * x = 8
x/10 = 8
Multiply both sides by 10
x=80
(b) The digit in the hundredths place is 0.09. It is 1/10 of 9 because...
1/10 * x = 0.09
x/10 = 0.09
Multiply both sides by 10
x=0.9
(c) The digit in the tens place is 80. We can divide it by 10 to find that it is 10 times as much as 8.
(d) The digit in the tenths place is 0.9. We can divide it by 10 to find that it is 10 times as much as 0.09.
