Answer:

10:40

Step-by-step explanation:

Step 1: Reduce ratio to lowest value

3 : 12 = 1 : 4

<em>*Divide by </em>3

Step 2: Solve ratio

<em>Let 'x' represent the second number </em>

1 : 4 = 10 : x

<em>Multiple the left side by 10</em>

10 : 40 = 10 : x

Therefore the second number in the ratio with 10 is 40
