Answer:
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
