(i) We have,

0.5 or 0.05

Firstly, we have to convert these decimals into equivalent fractions:

So,

0.5 =

=

=

And,

0.05 =

Now, from the above fractions it can be observed that both have same denominator

Since,

50 > 5

Therefore,

0.5 > 0.05

(ii) We have,

0.7 or 0.5

Firstly, we have to convert these decimals into equivalent fractions:

So,

0.7 =

And,

0.5 =

Now, from the above fractions it can be observed that both have same denominator

Since,

7 > 5

Therefore,

0.7 > 0.5

(iii) We have,

7 or 0.7

Firstly, we have to convert these decimals into equivalent fractions:

So,

7 =

=

=

And,

0.7 =

Now, from the above fractions it can be observed that both have same denominator

Since,

70 > 7

Therefore,

7 > 0.7

(iv) We have,

1.37 or 1.49

Firstly, we have to convert these decimals into equivalent fractions:

So,

1.37 =

And,

1.49 =

Now, from the above fractions it can be observed that both have same denominator

Since,

137 < 149

Therefore,

1.37 < 1.49

(v) We have,

2.03 or 2.30

Firstly, we have to convert these decimals into equivalent fractions:

So,

2.03 =

And,

2.30 =

Now, from the above fractions it can be observed that both have same denominator

Since,

203 < 230

Therefore,

2.03 < 2.30

(vi) We have,

0.8 or 0.88

Firstly, we have to convert these decimals into equivalent fractions:

So,

0.8 =

=

=

And,

0.88 =

Now, from the above fractions it can be observed that both have same denominator

Since,

80 < 88

Therefore,

0.8 < 0.88
