Fraction of a Number

In this video tutorial, Sam is tasked with painting a fence with 250 boards, 2/5 of which are already painted. The video explains two methods to calculate how many boards are painted: the first method involves multiplying the total number of boards by the fraction's numerator and then dividing by the denominator, while the second method involves dividing the total number of boards by the fraction's denominator and then multiplying by the numerator. Both methods yield the same result, showing that 100 boards are already painted. The video concludes with a recap of both methods and encourages Sam to start painting.
