Answer:
12
Explanation:
You could think of ratios as fractions :
Whatever we do to the top we must do to the bottom to keep it equivalent .
If we multiply the first thing by something we must do the multiply by the same number to the second.
2 × m = 8
m = 4
3 × m = ?
m = 4
3 × 4 = 12
? = 12
So the number that makes the ratio equivalent is 12
2:3 = 8:12
