Answer:
C. 6kg to 7kg(is the old one)
Solving steps:
Answer:
60 : 72 = 5 : 6
Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 60 and 72 is 12
Divide both terms by the GCF, 12:
60 ÷ 12 = 5
72 ÷ 12 = 6
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 120 and 144 is 24
Divide both terms by the GCF, 24:
120 ÷ 24 = 5
144 ÷ 24 = 6
The ratio 120 : 144 can be reduced to lowest terms by dividing both terms by the GCF = 24 :
120 : 144 = 5 : 6
Therefore:
120 : 144 = 5 : 6
A) The ratio 60 : 72 can be reduced to lowest terms by dividing both terms by the GCF = 12 :
60 : 72 = 5 : 6
Therefore:
60 : 72 = 5 : 6
Answer:
30 : 36 = 5 : 6
b) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 30 and 36 is 6
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
Therefore:
30 : 36 = 5 : 6
Answer:
6 : 7 = 6 : 7
c) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 6 and 7 is 1
Divide both terms by the GCF, 1:
6 ÷ 1 = 6
7 ÷ 1 = 7
The ratio 6 : 7 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
6 : 7 = 6 : 7
Answer:
15 : 18 = 5 : 6
d) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 15 and 18 is 3
Divide both terms by the GCF, 3:
15 ÷ 3 = 5
18 ÷ 3 = 6
The ratio 15 : 18 can be reduced to lowest terms by dividing both terms by the GCF = 3 :
15 : 18 = 5 : 6
Therefore:
15 : 18 = 5 : 6
Answer:
5 : 6 = 5 : 6
e) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 5 and 6 is 1
Divide both terms by the GCF, 1:
5 ÷ 1 = 5
6 ÷ 1 = 6
The ratio 5 : 6 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
5 : 6 = 5 : 6
