Write the ratio 12 : 36 as an equivalent ratio of x : 3.
To write the ratio 12 : 36 as an equivalent ratio of x:3, we need to find the value of x that gives us the same ratio.
We know that the ratio 12 : 36 can be simplified by dividing both numbers by their greatest common factor, which is 12.
12 : 36
= 1 : 3
This means that we need to find a value of x that when multiplied by 3 gives us 36 (the second number in our simplified ratio).
3x = 36
Solving for x:
3x/3 = 36/3
x = 12
Therefore, the ratio 12:36 is equivalent to the ratio 4:12 or x:3 where x = 12.
