Problem 1 :
3/5 ÷ 7/10
Solution :
= 3/5 ÷ 7/10
Since we change the division sign to multiplication sign. We have to write the reciprocal of 7/10.
= 3/5 ⋅10/7
= 30/35
HCF of 30 and 35 is 5. Dividing both numerator and denominator by 5.we get,
= 6/7
Problem 2 :
3/8 ÷ 6/11
Solution :
= 3/8 ÷ 6/11
Since we change the division sign to multiplication sign. We have to write the reciprocal of 6/11.
= 3/8 ⋅ 11/6
= 33/48
HCF of 33 and 48 is 3. Dividing both numerator and denominator by 3.we get,
= 11/16
Problem 3 :
4/15 ÷ 2/5
Solution :
= 4/15 ÷ 2/5
Since we change the division sign to multiplication sign. We have to write the reciprocal of 2/5.
= 4/15 ⋅ 5/2
= 20/30
HCF of 20 and 30 is 10. Dividing both numerator and denominator by 10.we get,
= 2/3
Problem 4 :
2/5 ÷ 4
Solution :
= 2/5 ÷ 4
Since we change the division sign to multiplication sign. We have to write the reciprocal of 4.
= 2/5 ⋅ 1/4
= 2/20
HCF of 2 and 20 is 2. Dividing both numerator and denominator by 2.we get,
= 1/10
Problem 5 :
1 ÷ 3/5
Solution :
= 1 ÷ 3/5
Since we change the division sign to multiplication sign. We have to write the reciprocal of 3/5.
= 1 ⋅ 5/3
= 5/3
Converting the improper fraction to mixed fraction, we get
= 1 2/3
Problem 6 :
1 1/3 ÷ 3/8
Solution :
= 1 1/3 ÷ 3/8
Converting the mixed fraction to improper fraction, we get
= 4/3 ÷ 3/8
Since we change the division sign to multiplication sign. We have to write the reciprocal of 3/8.
= 4/3 ⋅ 8/3
= 32/9
Converting the improper fraction to mixed fraction, we get
= 3 5/9
Problem 7 :
2/3 ÷ 1 1/2
Solution :
= 2/3 ÷ 1 1/2
Converting the mixed fraction to improper fraction, we get
= 2/3 ÷ 3/2
Since we change the division sign to multiplication sign. We have to write the reciprocal of 3/2.
= 2/3 ⋅ 2/3
= 4/9
Problem 8 :
2 1/4 ÷ 1 2/3
Solution :
= 2 1/4 ÷ 1 2/3
Converting the mixed fraction to improper fraction, we get
= 9/4 ÷ 5/3
Since we change the division sign to multiplication sign. We have to write the reciprocal of 5/3.
= 9/4 ⋅ 3/5
= 27 /20
Converting the improper fraction to mixed fraction, we get
= 1 7/20
