Answer:
2.No
3.No
4.No
5.No
Step-by-step explanation:
2. 60:400 and 60:120
Divide or simplify them
60 ÷ 20 = 3
400 ÷ 20 = 20
1:10
Then the other one
60:120
Divide or simplify them
120 ÷ 20 = 6 ÷ 2 = 3
4000 ÷ 20 = 200 ÷ 2 = 100
So its not
3:20 = 3:100
3. 12:4 and 42:158
Divide or simplify them
4 ÷ 4 = 1
12 ÷ 4 = 3
Then the other one
42 ÷ 2 = 21
158 ÷ 2 = 79
So it's not
1:3 = 21:79
4. 3:14 and 12:58
Divide or simplify them
The 3:14 is cannot be simplified so its still the same
Divide or simplify them
12 ÷ 2 = 6
58 ÷ 2 = 29
So it's not
3:14 = 6:29
5. 6:3 and 4:60
6 ÷ 3 = 2
3 ÷ 3 = 1
then the other one
4 ÷ 4 = 1
60 ÷ 4 = 15
So its not again
2:1 = 1:15
Hope this helps ^_^
