To do this, nice it to add 3 and 5, then divide 72 by the result of sum 3 and 5. Finally multiply it by 3 and by 5 to get the result. Lets do this 3+5=8 72:8=9 - number of rolls in 1 "unit" 9 3=27 - first group 9 5=45 - second group
To divide 72 rolls in a 3 to 5 ratio, first sum the parts of the ratio to get 8. Then, divide 72 by 8 to find that each part equals 9, leading to 27 rolls in the first group and 45 rolls in the second group. Thus, the rolls are divided into groups of 27 and 45, respectively.
