Lower Elementary:
Question: Isaac replaces the six strings on his guitar once every 3 months. How many new guitar strings will he need over the course of 4 years?
Answer: 96 strings
Solution: Since 3 months goes into 12 months 4 times, Isaac replaces 6 + 6 + 6 + 6 = 24 strings in one year. In four years, he replaces 24 + 24 + 24 + 24 = 96 strings. So, Isaac needs 96 new strings.
