Answer: The second number is 40.
Step-by-step explanation:
Let x be the second number. We can create another ratio and cross-multiply since this is an equivalent ratio table.
Given:
[tex]\displaystyle \frac{3}{12} =\frac{10}{x}[/tex]
Cross-multiply:
3 * x = 12 * 10
3x = 120
Divide both sides of the equation by 3:
x = 40
