Answer :
We need to divide 72 rolls into 2 groups so that their ratio is 3:5. First, we can see that the ratio of 3:5 tells us there is 8 separate groups of rolls. Now its easy, since we have 72 rolls and we need to divide them into 8 equal groups: 72/8=9. So each group has 9 rolls. Now we separate them into groups with the ratio 3:5, so: 3*9:5*9 and that is: 27 rolls and 45 rolls.
Answer:
27 and 45
Step-by-step explanation:
3:5 turns into 3+5 which equals 8. After that all you do is divide 72 by 8 and you get 9. Since we have 3 and 5 as the ratio you have to do 3*9 and 5*9. Thats how we get 27 and 45.
Hope I helped!!! :D Ask me any questions if you don't understand!
Oh, and a ratio is basically a fraction. So 3:5 is acually 3/5 too!
