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
