Answer: 12x/20
Step-by-step explanation:
Looking at 3x/5
The expression equivalent is 12x/20
The reason is this
12x/20
If you divide the 12x by 4
It will give you 3x
If you divide 20 by 4
It will give you 5
Therefore, you will still have 3x/5
Another way to look at it is this
3x/5= 0.6x
12x/20= 0.6x
Therefore, the final answer is b which is 12x/20
