Let’s check which ratio is greater

2 : 1 or 1 : 2

To check,

we write ratio in fraction form

2/1 or 1/2

So, we have to find greater of 2/1 & 1/2

First, we make denominator same

Common denominator = LCM of 1 & 2

= 2

Thus,

2/1 = 2/1 × 2/2 = 4/2

1/2 = 1/2

So,

4/2 > 1/2

i.e. 2/1 > 1/2

∴
**
2 : 1 is greater ratio
**

####
**
Compare 4 : 2 & 3 : 2
**

Writing ratio in fraction form

4/2 & 3/2

Here denominator are same

Now, number with greater numerator is greater,

4/2 > 3/2

∴ 4 : 2 > 3 : 2

**
So, 4
**
**
:
**
**
2
**
**
is
**
**
the greater
**
**
ratio
**

####
**
Compare 7 : 3 & 5 : 2
**

Writing ratio in fraction form

7/3 & 5/2

First, we have to make denominator same,

Common denominator = L.C.M of 3 & 2

= 2 × 3

= 6

Thus,

7/3 = 7/3 × 2/2 = 14/6

5/2 = 5/2 × 3/3 = 15/6

So,

14/6 < 15/6

7 : 3 < 5 : 2

**
So
**
**
,
**
**
5
**
**
: 2
**
**
is the
**
**
greater ratio
