Simplifying Ratios

20:10

30:36

54:12

Simplify

1. 20:10 = 2:1

2. 30:36 = 5:6

3. 54: 12 = 18:7

Step-by-step explanation:

Answer for Number 1

The GCF of 20 and 10 is 10

Divide both by the GCF, 10:

20 : 10 = 2

10 : 10 = 1

The ratio 20 : 10 can be reduced t by dividing both terms by the GCF = 10

20 : 10 = 2 : 1

20:10 is 2:1

30:36 is 5:6

54:12 is 9:2

Step-by-step explanation:

First one is Divide both terms by the GCF, 10:

20 : 10 = 2

10 : 10 = 1

The ratio 20 : 10 can be reduced to lowest terms by dividing both terms by the GCF = 10:

20 : 10 = 2 : 1

Second is Divide both terms by the GCF, 6:

30 : 6 = 5

36 : 6 = 6

The ratio 30 : 36 can be reduced to lowest terms by dividing both terms by the GCF = 6:

30 : 36 = 5 : 6

Third is Divide both terms by the GCF, 6:

54 : 6 = 9

12 : 6 = 2

The ratio 54 : 12 can be reduced to lowest terms by dividing both terms by the GCF = 6:

54 : 12 = 9 : 2
