Question

bridget has softball practice every 3rd day and lacrosse every 6th day. if she has both today in ho many days will she have both again

Answer 1

Hi Jenny,

ACT math is all about speed and accuracy, and the fastest and most certain way to answer this question correctly is to draw out a little chart. Let's say day 0 is when Bridget last had lacrosse and softball on the same day. If she has softball every 3 days and lacrosse every 6 days, then the diagram below shows the next time she will have both on the same day. 6 days later is the next time she'd have both sports on the same day.

Day 0, 1, 2, 3, 4, 5, 6

Lacrosse X X

Softball X X X

Answer 2

What is the least common multiple, LCM, of 3 and 6?
