Which is greater?
(i) 0.5 or 0.05 (ii) 0.7 or 0.5 (iii) 7 or 0.7
(iv) 1.37 or 1.49 (v) 2.03 or 2.30 (vi) 0.8 or 0.88
To check whether a decimal is greater than or smaller than the other decimal, we first convert them into like fractions then compare.
Solution:
(i) 0.5 or 0.05
0.5 _ 0.05
5/10 _ 5/100
Converting decimals them into like fractions, we get
5/10 × 10/10 _ 5/100× 1/1
50/100 > 5/100
0.5 > 0.05
Therefore,0.5 is greater than 0.05.
ii) 0.7 or 0.5
7/10 _ 5/10
Hence, 7/10 > 5/10
Therefore,0.7 is greater than 0.5.
iii) 7 or 0.7
7 _ 7/10
7/1 × 10/10 _ 7/10
70/10 > 7/10
Hence ,7 > 0.7.
Therefore, 7 is greater.
iv) 1.37 or 1.49
137/100 _ 149/100
137/100 < 149/100
Therefore, 1.37 < 1.49
Hence, 1.49 is greater.
v) 2.03 or 2.30
203/100 _ 230/100
203/100 < 230/100
Therefore, 2.03 < 2.30
Hence, 2.30 is greater.
vi) 0.8 or 0.88
8/10 _ 88/100
Converting them into like fractions, we get
8/10 × 10/10 _ 88/100
80/100 < 88/100
Therefore, 0.8 < 0.88.
Hence, 0.88 is greater.
