Sagot :
Step-by-step explanation:
1.) 1 : 2
2 to 4
to simplify this ratio, we just have to find their GCF (greatest common factor)
the GCF of 2 and 4 is 2
2÷2 = 1
4÷2 = 2
thus the answer is 1 : 2
2.) 1 : 4
3 to 12
GCF 3
3÷3 = 1
12÷3 = 4
3.) 5 : 1
35:7 GCF 7
35÷7 = 5
7÷7 = 1
4.) 3 : 4
15 : 20
GCF 5
15÷5 = 3
20÷5 = 4
5.) 7 : 4
this is already in simpliest form since the GCF is only 1
