DSPM 0700 HOMEWORK (ASSIGNMENT 1, SECTION 1-1)
Show the following fractions as decimals:
1.
84
100
0.84 (Two decimal places)
2.
22
10,000
0.0022 (Four decimal places; need leading zeros for remaining places)
3. Sort the following numbers in order from smallest to largest: 76.3, 76.33, 75.9, 76,
76.124.
75.9, 76, 76.124, 76.3, 76.33
75 is the smallest whole number part, so 75.9 is the smallest number. 76 is
assumed to have the decimal point to the extreme right (i.e., 76. or 76.0) and it
would be smaller than any of the other decimals. 76.124 will be less than 76.3,
since the 1 in the tenths place is less than the 3. 76.3 and 76.33 are equal through
the tenths place; a 0 understood to be in the hundredths place (i.e., 76.30) is less
than the 3 in 76.33.
Round the following to the place value indicated:
4. 429,207; nearest ten thousand
The first 2 is the ten-thousands place. Next to it is a 9, so we round up by
adding 1 to the 2, making 3, and replacing all the digits beginning with
the 9 with zeros. The rounded number is 430,000.
5. 0.02847; nearest hundredth
The hundredth place is held by the 2. The 8 next to it says that we round up.
Add 1 to the 2 and drop the decimal places to the right. Therefore, the
rounded number is 0.03.
6. 82.152; nearest whole number
The nearest whole number is to the ones place. The digit in the tenths place
is 1, so we round down. Leave the 2 in the ones place alone and drop all the
decimal digits. The rounded number is 82.
