Division of decimal fractions by multiples of 10, 100, 1000 etc., are discussed here with different types of examples.
1. 245.1 ÷ 30
Solution:
245.1 ÷ 30
= 245.1/30
= 245.1/(3 × 10)
= (245.1/3) × (1/10)
= 81.7 × (1/10)
= 81.7/10
= 8.17
Therefore, 245.1 ÷ 30 = 8.17
2. 3421.83 ÷ 3000
Solution:
3421.83 ÷ 3000
= 3421.83/3000
= 3421.83/(3× 1000)
= (3421.83/3) × (1/1000)
= 1140.61 × (1/1000)
= 1140.61/1000
= 1.14061
Therefore, 3421.83 ÷ 3000 = 1.14061
3. 400.8 ÷ 400
Solution:
400.8 ÷ 400
= 400.8/400
= 400.8/(4 × 100)
= (400.8/4) × (1/100)
= 100.2 × (1/100)
= 100.2/100
= 1.002
Therefore,400.8 ÷ 400 = 1.002
4. 30.94 ÷ 70
Solution:
30.94 ÷ 70
= 30.94/70
= 30.94/(7 × 10)
= (30.94/7) × (1/10)
= 4.42 × (1/10)
= 4.42/10
= 0.442
Therefore, 30.94 ÷ 70 = 0.442
