1. 22:66

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 22 and 66 is 22

Divide both terms by the GCF, 22:

22 ÷ 22 = 1

66 ÷ 22 = 3

The ratio 22 : 66 can be reduced to lowest terms by dividing both terms by the GCF = 22 :

22 : 66 = 1 : 3

Therefore:

22 : 66 = 1 : 3

2. 7:49

The GCF of 7 and 49 is 7

Divide both terms by the GCF, 7:

7 ÷ 7 = 1

49 ÷ 7 = 7

The ratio 7 : 49 can be reduced to lowest terms by dividing both terms by the GCF = 7 :

7 : 49 = 1 : 7

Therefore:

7 : 49 = 1 : 7

3. 4:6

The GCF of 4 and 6 is 2

Divide both terms by the GCF, 2:

4 ÷ 2 = 2

6 ÷ 2 = 3

The ratio 4 : 6 can be reduced to lowest terms by dividing both terms by the GCF = 2 :

4 : 6 = 2 : 3

Therefore:

4 : 6 = 2 : 3

4. 6:15

The GCF of 6 and 15 is 3

Divide both terms by the GCF, 3:

6 ÷ 3 = 2

15 ÷ 3 = 5

The ratio 6 : 15 can be reduced to lowest terms by dividing both terms by the GCF = 3 :

6 : 15 = 2 : 5

Therefore:

6 : 15 = 2 : 5

5. 14:20

The GCF of 14 and 20 is 2

Divide both terms by the GCF, 2:

14 ÷ 2 = 7

20 ÷ 2 = 10

The ratio 14 : 20 can be reduced to lowest terms by dividing both terms by the GCF = 2 :

14 : 20 = 7 : 10

Therefore:

14 : 20 = 7 : 10

6. 33:44

The GCF of 33 and 40 is 1

Divide both terms by the GCF, 1:

33 ÷ 1 = 33

40 ÷ 1 = 40

The ratio 33 : 40 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

33 : 40 = 33 : 40

7. 48:54

The GCF of 48 and 54 is 6

Divide both terms by the GCF, 6:

48 ÷ 6 = 8

54 ÷ 6 = 9

The ratio 48 : 54 can be reduced to lowest terms by dividing both terms by the GCF = 6 :

48 : 54 = 8 : 9

Therefore:

48 : 54 = 8 : 9

8. 200:250

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 200 and 250 is 50

Divide both terms by the GCF, 50:

200 ÷ 50 = 4

250 ÷ 50 = 5

The ratio 200 : 250 can be reduced to lowest terms by dividing both terms by the GCF = 50 :

200 : 250 = 4 : 5

Therefore:

200 : 250 = 4 : 5
