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
Answer:
A
Step-by-step explanation:
write it as a ratio
11:6 = 110: x
cross multiply
11x= 660
divide by 11 on both sides
x= 60
