Answer 2
Answer: It would take 15 minutes.
21/7=3
5/3=1.666666666667
1.6666666667*3= 5
5*3=15 

So if you do 21 divied by 7 that equals 3. then you do 5 divied by 3=1.666666666667 you divide the 3 bc that's the answer you got for 21/7. then you do 1.666666666667 x3. bc you had that answer for the last problem. then you just have 2 multiply 5x3 and that equals 15.

The ratio of adults to children at a picnic is 4 to 5. The total number of people at the picnic is 27. How many adults and children are at the picnic? Include steps.

Answers

There are 12 children and 15 adults at the picnic.

Add together the ratios 4 and 5 and divide the amount of people by that number (so 27 divided by 9)

You then get 3. So then multiply both sides of your ratio by 3. (4:5 ----> 12:15)
