Answer:
Step-by-step explanation:
Here's the answer
16.) 12:21 = 4:7
17.) 6:42 = 1:7
18.) 12:48 = 1:4
19.) 20:45 = 4:9
20.) 9:18 = 1:2
16.) Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 12 and 21 is 3
Divide both terms by the GCF, 3:
12 ÷ 3 = 4
21 ÷ 3 = 7
The ratio 12 : 21 can be reduced to lowest terms by dividing both terms by the GCF = 3 :
12 : 21 = 4 : 7
Therefore:
17.) Reduce the ratio further with the greatest common factor (GCF).
The GCF of 6 and 42 is 6
Divide both terms by the GCF, 6:
6 ÷ 6 = 1
42 ÷ 6 = 7
The ratio 6 : 42 can be reduced to lowest terms by dividing both terms by the GCF = 6 :
6 : 42 = 1 : 7
18.) Reduce the ratio further with the greatest common factor (GCF).
The GCF of 12 and 48 is 12
Divide both terms by the GCF, 12:
12 ÷ 12 = 1
48 ÷ 12 = 4
The ratio 12 : 48 can be reduced to lowest terms by dividing both terms by the GCF = 12 :
12 : 48 = 1 : 4
19.) Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 20 and 45 is 5
Divide both terms by the GCF, 5:
20 ÷ 5 = 4
45 ÷ 5 = 9
The ratio 20 : 45 can be reduced to lowest terms by dividing both terms by the GCF = 5 :
20 : 45 = 4 : 9
20. Try to reduce the ratio further with the greatest common factor (GCF)
The GCF of 9 and 18 is 9
Divide both terms by the GCF, 9:
9 ÷ 9 = 1
18 ÷ 9 = 2
The ratio 9 : 18 can be reduced to lowest terms by dividing both terms by the GCF = 9 :
9 : 18 = 1 : 2
