## Ratios in Simplest Form Questions and Answers

**Example 1. **

Express each of the following ratios in the simplest form

(i) 10 : 50

(ii) 2/7: 3/7

(iii) 6 : 18

(iv) 5 : 1 1/2

(v) 24 : 36

(vi) 22 : 55

(vii) 42 : 56

(viii) 250 : 300

**Solution:**

(i) 10:50

When we divide by 10 we get,

10/10:50/10

1:5

Hence, the simplest form of 10:50 is 1:5.

(ii) 2/7:3/7

When we divide by 7 we get,

2/7:3/7

2:3

Hence, the simplest form of 2/7:3/7 is 2:3.

(iii) 6:18

When we divide by 6 we get,

6/6:18/6

1:3

Hence, the simplest form of 6:18 is 1:3.

(iv) 6: 1 1/2

Converting the second part 1 1/2 as an improper fraction, we get

= 6 : 3/2

Multiplying both parts by 2, we get

= 6 ⋅ 2 : (3/2) ⋅ 2

= 12 : 3

Dividing by 3, we get

= 4 : 1

So, the simplest form is 4: 1.

(v) 24:36

When we divide by 6 we get,

24/6:36/6

4:6

When we divide by 2 we get,

=2:3

Hence, the simplest form of 24:36 is 2:3.

(vi) 22:55

When we divide by 11 we get,

22/11:55/11

2:5

Hence, the simplest form of 22:55 is 2:5.

(vii) 42:56

When we divide by 7 we get,

42/7:56/7

6:8

When we divide by 2 we get,

3:4

200 cm:60 cm

20 cm:6 cm

Divide with 2, we get

20/2 cm:6/2 cm

10 :3

(iv) 3 minutes : 50 seconds

we know that 1 minute=60 seconds.

180 seconds: 50 seconds

18:5

(v) 2 hour : 40 minutes

we know that 1 hour=60 minutes.

120 minutes:40 minutes

By dividing with 4 we get,

3:1

(vi) 3 minutes : 50 seconds

we know that 1 minute=60 seconds.

180 seconds:50 seconds

18:5

(vii) 50 kg: 1 quintal

we know that 1 quintal=1000 kg

50 kg:1000 kg

divide with 50 we get,

1:20

(viii) 50 paise : 1 Rupee

we know that 1 rupee=100 paise.

50 paise:100 paise

Divide with 50, we get

1 paise:2 paise

(ix) 75 cm : 3 m

we know that 1m=100 cm.

75 cm: 300 cm

By dividing with 75 we get,

1:4

(X) 300 m: 6 km
