Question

Bridget has swimming lessons every sixth day and diving lessons every fourth day. If she had a swimming lesson and a diving lesson on May 7 , in how many days will she have both swimming and diving lessons?

Answer 1

4 = 2 × 2

6 = 2 × 3

LCM of 4 × 6 = 2 × 2 × 3 = 12

Bridget will next have both swimming and diving lessons in 12 days, on May 19.
