Decimal Multiplication Word Problems Challenge

The video tutorial covers solving word problems involving decimal multiplication. It starts with calculating costs for school lunches over multiple weeks, followed by determining earnings based on hourly rates and hours worked. The tutorial then addresses a fuel efficiency problem, calculating distance based on miles per gallon and tank capacity. It also includes a biking distance problem, calculating weekly distance based on daily rides. Finally, a multi-step problem is presented, calculating total vacation costs for a family visiting two parks.
