To solve the problems in the worksheet, we need to divide each number by 10, 100, or 1000. Dividing by these numbers involves moving the decimal point to the left by a specific number of places:
-
Dividing by 10: Move the decimal point
1 place to the left.
-
Dividing by 100: Move the decimal point
2 places to the left.
-
Dividing by 1000: Move the decimal point
3 places to the left.
Let's solve each problem step by step:
---
1) \( 62 \div 10 \)
- Move the decimal point 1 place to the left: \( 62.0 \rightarrow 6.2 \)
-
Answer: \( 6.2 \)
2) \( 672 \div 1000 \)
- Move the decimal point 3 places to the left: \( 672.0 \rightarrow 0.672 \)
-
Answer: \( 0.672 \)
3) \( 122 \div 100 \)
- Move the decimal point 2 places to the left: \( 122.0 \rightarrow 1.22 \)
-
Answer: \( 1.22 \)
4) \( 898 \div 10 \)
- Move the decimal point 1 place to the left: \( 898.0 \rightarrow 89.8 \)
-
Answer: \( 89.8 \)
5) \( 1089 \div 100 \)
- Move the decimal point 2 places to the left: \( 1089.0 \rightarrow 10.89 \)
-
Answer: \( 10.89 \)
6) \( 979 \div 100 \)
- Move the decimal point 2 places to the left: \( 979.0 \rightarrow 9.79 \)
-
Answer: \( 9.79 \)
7) \( 4617 \div 1000 \)
- Move the decimal point 3 places to the left: \( 4617.0 \rightarrow 4.617 \)
-
Answer: \( 4.617 \)
8) \( 55 \div 10 \)
- Move the decimal point 1 place to the left: \( 55.0 \rightarrow 5.5 \)
-
Answer: \( 5.5 \)
9) \( 113 \div 100 \)
- Move the decimal point 2 places to the left: \( 113.0 \rightarrow 1.13 \)
-
Answer: \( 1.13 \)
10) \( 199 \div 100 \)
- Move the decimal point 2 places to the left: \( 199.0 \rightarrow 1.99 \)
-
Answer: \( 1.99 \)
11) \( 62 \div 1000 \)
- Move the decimal point 3 places to the left: \( 62.0 \rightarrow 0.062 \)
-
Answer: \( 0.062 \)
12) \( 100 \div 1000 \)
- Move the decimal point 3 places to the left: \( 100.0 \rightarrow 0.100 \) (or simply \( 0.1 \))
-
Answer: \( 0.1 \)
13) \( 1169 \div 100 \)
- Move the decimal point 2 places to the left: \( 1169.0 \rightarrow 11.69 \)
-
Answer: \( 11.69 \)
14) \( 10 \div 100 \)
- Move the decimal point 2 places to the left: \( 10.0 \rightarrow 0.10 \) (or simply \( 0.1 \))
-
Answer: \( 0.1 \)
15) \( 522 \div 10 \)
- Move the decimal point 1 place to the left: \( 522.0 \rightarrow 52.2 \)
-
Answer: \( 52.2 \)
16) \( 29 \div 100 \)
- Move the decimal point 2 places to the left: \( 29.0 \rightarrow 0.29 \)
-
Answer: \( 0.29 \)
17) \( 36 \div 10 \)
- Move the decimal point 1 place to the left: \( 36.0 \rightarrow 3.6 \)
-
Answer: \( 3.6 \)
18) \( 666 \div 1000 \)
- Move the decimal point 3 places to the left: \( 666.0 \rightarrow 0.666 \)
-
Answer: \( 0.666 \)
---
