Q: Why a number can be a digit, but every digit is not a number?
First, understand the difference:
Digit = a single symbol (0–9)
Number= a value made using one or more digits
, Key Idea:
👉 A “digit is like a letter”.
👉 A “number is like a word”.
Examples:
• 5
✔ It is a **digit**
✔ It is also a **number** (because a single digit can form a
number)
• **56** →
✔ It is a **number**
❌ It is NOT a digit (because it has more than one digit: 5 and 6)
Q2:Why every whole number can be written as fraction with
denominator 1?
AAnswer:
This is because dividing any whole number by 1 gives the same
number.
Example:
𝟏𝟕
= 𝟏𝟕
𝟏
Hence, whole numbers can be expressed in fractional form with
denominator 1.
Q3:Why one is not considered as a prime number?
