Super Simple Explanation Of Questions with Examples
1. Is zero a rational number? Can you write it in the form p/q where p and q are integers and q ≠ 0?
👉 First, let’s understand what a rational number is.
A rational number is a number that can be written in the form of p/q, where:
- p (the top number) and q (the bottom number) are whole numbers or negative numbers.
- q (the bottom number) should not be 0, because division by 0 is not allowed.
Now, let’s check if 0 can be written in this form.
✅ Yes! We can write 0 as:
0 = 0⁄1,
0 = 0⁄2,
0 = 0⁄5,
0 = 0⁄100,
0 = 0⁄-3
📌 Here, p = 0 and q is any non-zero number. Since this follows the rule of a rational number, zero is a rational number.
💡 Real-life example:
Imagine you have zero chocolates and you divide them among 5 friends.
Each friend gets 0 chocolates (0/5 = 0).
This means 0 is a rational number because it can be written as a fraction! ✅
2. Find six rational numbers between 3 and 4.
We need to find any six numbers between 3 and 4. These numbers should be bigger than 3 but smaller than 4.
Step 1: Pick decimal numbers between 3 and 4
✅ Examples:
3.1, 3.2, 3.3, 3.5, 3.7, 3.9
Step 2: Convert these into fractions
- 3.1 = 31/10
- 3.2 = 32/10
- 3.3 = 33/10
- 3.5 = 35/10
- 3.7 = 37/10
- 3.9 = 39/10
💡 Real-life example:
- Imagine you have 3 full chocolates and your friend has 4 chocolates.
- Between them, there are chocolates like 3.1, 3.5, 3.9 chocolates.
- These are the numbers between 3 and 4! ✅
3. Find five rational numbers between 3/4 and 5/5.
👉 First, let’s understand these numbers:
3/4=0.75, 5/5=1.00
We need numbers between 0.75 and 1.00.
✅ Step 1: Choose some numbers between 0.75 and 1.00
0.76, 0.8, 0.85, 0.9, 0.95
✅ Step 2: Convert these into fractions
- 0.76 = 76/100
- 0.8 = 8/10
- 0.85 = 85/100
- 0.9 = 9/10
- 0.95 = 95/100
💡 Real-life example:
- Imagine you drink 3/4 (0.75) of a glass of water but not the full glass (1.0).
- Between them, you have different amounts like 0.8, 0.85, 0.9 glass of water.
- These are the numbers between 3/4 and 1 (5/5)! ✅
4. True or False Questions
(i) Every natural number is a whole number.
✔ True.
👉 Natural numbers are:
1,2,3,4,5,6,…(counting numbers)1, 2, 3, 4, 5, 6, … \quad (\text{counting numbers})
👉 Whole numbers are:
0,1,2,3,4,5,6,…(counting numbers + 0)0, 1, 2, 3, 4, 5, 6, … \quad (\text{counting numbers + 0})
💡 Real-life example:
- Imagine you are counting apples: 1 apple, 2 apples, 3 apples…
- These are natural numbers.
- Whole numbers also include 0 (0 apples).
✅ Since every natural number is already in whole numbers, the statement is true.
(ii) Every integer is a whole number.
✖ False.
👉 Integers are:
…,−3,−2,−1,0,1,2,3,4,……, -3, -2, -1, 0, 1, 2, 3, 4, …
👉 Whole numbers are:
0,1,2,3,4,…0, 1, 2, 3, 4, …
📌 Negative numbers are in integers but not in whole numbers!
💡 Real-life example:
- If your bank account balance is -3 rupees, this means you owe money.
- -3 is an integer, but not a whole number.
❌ Since negative numbers are not whole numbers, the statement is false.
(iii) Every rational number is a whole number.
✖ False.
👉 Rational numbers are:
1/2, 3/4, 5/3, −2, 0, 1, 2, 3,…….
👉 Whole numbers are:
0, 1, 2, 3, 4,…
📌 Fractions like 1/2, 3/4, and 5/3 are rational but not whole numbers!
💡 Real-life example:
- If you eat half a pizza (1/2 pizza), this is a rational number but not a whole number.
- A whole number would be 1 full pizza, 2 pizzas, 3 pizzas, etc.
❌ Since rational numbers can be fractions, the statement is false.
Zero से Hero तक! 📢 Rational Numbers का धमाल! 🚀
🔥 क्या Zero भी Rational Number होता है? 🤯
Imagine करो कि तुम्हारे पास 0 chocolates हैं और तुम्हें इसे 5 दोस्तों में बांटना है. हर दोस्त को क्या मिलेगा? 🤔
✅ सिर्फ हवा! यानी Zero! 😆
Zero को हम fraction में लिख सकते हैं:
0=0/1, 0=0/2, 0=0/1000
📌 Rule: Rational number को हमेशा p/q के रूप में लिखा जा सकता है (जहाँ q ≠ 0 हो).
तो हां, Zero भी एक Rational Number है! ✅
🤔 3 और 4 के बीच में 6 मज़ेदार Numbers कौन से हैं?
सोचो कि तुम्हारे पास 3 chocolates हैं और तुम्हारे दोस्त के पास 4 chocolates. लेकिन क्या इसके बीच में कुछ और chocolates भी हो सकती हैं?
✅ हां! Example देखो:
3.1, 3.2, 3.3, 3.5, 3.7, 3.9
👉 इनको fraction में लिखें:
31/10, 32/10, 33/10, 35/10, 37/10, 39/10
💡 Fun Challenge:
👉 तुम 3 और 4 के बीच कोई 3 rational numbers सोच सकते हो? Comment में बताओ! 😍
🍕 3/4 और 5/5 के बीच 5 मजेदार Numbers!
अब सोचो तुम्हारे पास 1 पूरी pizza है. लेकिन तुम्हारा दोस्त सिर्फ 3/4 (75%) pizza खा सकता है. उसके और पूरी pizza (1) के बीच कौन-कौन से हिस्से होंगे? 🤔
✅ Examples:
0.76, 0.8, 0.85, 0.9, 0.95
👉 अब इन्हें fraction में लिखो:
76/100, 8/10, 85/100, 9/10, 95/100
💡 Fun Fact:
🍕 अगर तुमने Pizza 85% खा ली, तो तुमने 0.85 fraction खाई! 😂
✅ True या False? चलो दिमाग दौड़ाते हैं! 🤓
👉 Q1: हर Natural Number, Whole Number होता है?
✅ सही! (क्योंकि 1, 2, 3… सब Whole Numbers में आते हैं!)
👉 Q2: हर Integer, Whole Number होता है?
❌ गलत! (क्योंकि -3, -2, -1 भी Integer होते हैं, लेकिन Whole Number नहीं!)
👉 Q3: हर Rational Number, Whole Number होता है?
❌ बिलकुल नहीं! (क्योंकि ½, ¾ जैसे numbers भी Rational होते हैं, पर Whole नहीं!)
