Answer:
B. Every year the coin is worth 3 more dollars.
You can multiply 3 and 6 together then divide the product by 2
(6*3)/2=18/2=9
Step 1: Find the Lowest Common Multiple between the denominators.
Step 2: Multiply the numerator and denominator of each fraction by a number (the one that will get them to the lcm) so that they have the LCM as their new denominator.
Step 3: Add or subtract the numerators and keep the denominator the same.
