Question 1 of 50
1. Question
Topic: Standard form to Ordinary numbers.
Please have a pen and paper ready to show your workings 📝
Convert the following into an ordinary number:
5.67 × 10³
-
⌨️ Enter your answer in the provided field.
CorrectIncorrectHint
Rules for Converting Standard Form to Ordinary Numbers
Standard form is written as:
A × 10n, where 1.0 ≤ A < 10.0 and n is an integer.
Key points:
- If the power (n) is positive: Move the decimal point n places to the right. This makes the number larger.
- If the power (n) is negative: Move the decimal point |n| places to the left. This makes the number smaller.
Tip: Add extra zeros to help visualize the jumps of the decimal point.
Examples:
Positive Power: 3.4 × 104
Start with 3.4. Add zeros: 3.4000. Move the decimal 4 places to the right → 34000.
Negative Power: 4.2 × 10-3
Start with 4.2. Add zeros: 0004.2. Move the decimal 3 places to the left → 0.0042.
Tip: Always count your decimal jumps carefully and double-check your final answer!

- If the power (n) is positive: Move the decimal point n places to the right. This makes the number larger.
- If the power (n) is negative: Move the decimal point |n| places to the left. This makes the number smaller.
Tip: Add extra zeros to help visualize the jumps of the decimal point.
Examples:
Positive Power: 3.4 × 104
Start with 3.4. Add zeros: 3.4000. Move the decimal 4 places to the right → 34000.
Negative Power: 4.2 × 10-3
Start with 4.2. Add zeros: 0004.2. Move the decimal 3 places to the left → 0.0042.
Tip: Always count your decimal jumps carefully and double-check your final answer!

Rules for Converting Standard Form to Ordinary Numbers
Standard form is written as:
A × 10n, where 1.0 ≤ A < 10.0 and n is an integer.
Key points:
- If the power (n) is positive: Move the decimal point n places to the right. This makes the number larger.
- If the power (n) is negative: Move the decimal point |n| places to the left. This makes the number smaller.
Tip: Add extra zeros to help visualize the jumps of the decimal point.
Examples:
Positive Power: 3.4 × 104
Start with 3.4. Add zeros: 3.4000. Move the decimal 4 places to the right → 34000.
Negative Power: 4.2 × 10-3
Start with 4.2. Add zeros: 0004.2. Move the decimal 3 places to the left → 0.0042.
Tip: Always count your decimal jumps carefully and double-check your final answer!
