From the question, we are informed that Billy has 2.4 m of ribbon for crafts and that he wants to share it evenly with 12 friends.
The number of centimeters of ribbon that each of the 7 friends would get will be gotten by dividing 2.4m by 12. We can solve this by first converting 2.4meters to centimeters. This will be:
Step-by-step explanation: 2/5 = 4/10 = 12/30 This means that the machine cuts out 12m lengths for every roll now you just take 400/12 and you get your answer. Now 400/12 will be 33,333... So just round it up to how many she needs aka 34
