Mrs. Evans has 120 crayons and 30 pieces of paper to give to her students. What is the largest number of students she can have in her class so that each student gets an equal number of crayons and an equal number of paper?
I will use LCM because I have to find a common multiple of crayons & paper.
I will use Highest common factor because I have to divide the crayons and paper amongst the students
Rosa is making a game board that is 16 inches by 24 inches. She wants to use square tiles. What is the largest size of tile she can use?
I want to find the largest size of tile so I will use LCM of 16 and 24
I want to find the largest size of tile formed by dividing the game board into equal squares, so I will use HCF
Zeta gave away a $100 bill for every 100th caller. Every 30th caller received free concert tickets. How many callers must get through before one of them get both a concert and a $100 bill?
I want to find the total number of callers before one of them gets both a concert ticket & a 100$ bill, so I will find the LCM.
I want to divide $100 and 30 into equal parts so I will use HCF
Two bikers are riding a circular path. The first rider completes a round in 12 minutes. The second rider completes a round in 18 minutes. If they both started at the same place and time and go in the same direction, after how many minutes will they meet again at the starting point?
I have to find the exact time at which both bikers meet at the starting point so I will use LCM
I have to find the exact time at which both bikers meet at the starting point so I will use HCF
Sean has 8-inch pieces of toy train track and Ruth has 18-inch pieces of train track. How many of each piece would each child need to build tracks that are equal in length?
I want to find a common multiple of 8 & 18 to build tracks that are equal in length so I will use LCM
I want to find the common factor of 8 and18 to get the answer so I will use HCF
