c. 70.006
d. 86.06
e. 0.77
f. 11.23
g. 0.041
h. 276.208
The expanded form of a decimal number represents each digit of the number according to its place value. Here are the expanded forms for the given decimal numbers:
a. For 94.023: $$ 90 + 4 + 0.02 + 0.003 = 90 + 4 + \frac{2}{100} + \frac{3}{1000} $$
b. For 8.15: $$ 8 + 0.1 + 0.05 = 8 + \frac{1}{10} + \frac{5}{100} $$
c. For 70.006: $$ 70 + 0.006 = 70 + \frac{6}{1000} $$
d. For 86.06: $$ 80 + 6 + 0.06 = 80 + 6 + \frac{6}{100} $$
e. For 0.77: $$ 0.7 + 0.07 = \frac{7}{10} + \frac{7}{100} $$
f. For 11.23: $$ 10 + 1 + 0.2 + 0.03 = 10 + 1 + \frac{2}{10} + \frac{3}{100} $$
g. For 0.041: $$ 0.04 + 0.001 = \frac{4}{100} + \frac{1}{1000} $$
h. For 276.208: $$ 200 + 70 + 6 + 0.2 + 0.008 = 200 + 70 + 6 + \frac{2}{10} + \frac{8}{1000} $$
These representations show each digit specifically according to its place value in the number.

Circle the odd one out in each of the following.
a. $5.9 ; 7.6 ; 0.11$
b. $1.12 ; 3.5 ; 8.09$
c. $9.8 ; 5.43 ; 2.0$
d. $3.0,9.97,1.8$
e. $5.15,7.33,9.0$
f. $4,2.0,1.5$
To find the odd one out among numbers, we can look at various properties such as whole numbers vs. decimal numbers, or inconsistencies in decimal places. Let's analyze each option one by one based on the number of decimal places and type of numbers (whole or decimal):
-
a. $5.9 ; 7.6 ; 0.11$
- $5.9$ and $7.6$ each have one decimal place, while $0.11$ has two decimal places.
- Odd one out: $0.11$
-
b. $1.12 ; 3.5 ; 8.09$
- $1.12$ and $8.09$ each have two decimal places, while $3.5$ has one decimal place.
- Odd one out: $3.5$
-
c. $9.8 ; 5.43 ; 2.0$
- $9.8$ and $2.0$ each have one decimal place, while $5.43$ has two decimal places.
- Odd one out: $5.43$
-
d. $3.0,9.97,1.8$
- $3.0$ and $1.8$ each have one decimal place, while $9.97$ has two decimal places.
- Odd one out: $9.97$
-
e. $5.15,7.33,9.0$
- $5.15$ and $7.33$ each have two decimal places, while $9.0$ has one decimal place.
- Odd one out: $9.0$
-
f. $4,2.0,1.5$
- $4$ is a whole number while $2.0$ and $1.5$ are decimal numbers.
- Odd one out: $4$
Therefore, these are the odd items for each of the groups based on the differences in the number of decimal places.
Convert the following unlike decimals to like decimals.
