Answer:
Number of rats : Food weight = 1 : 5
Step-by-step explanation:
Number of rats in the group = 9
Weight of food carried away by them = 45 kg
Ratio of the number of rats and food weight = 
= 
= 
= 
Therefore, Number of rats : Food weight = 1 : 5
There is a 50% probability.
First add up all of the sections to get a total.
10 Green + 15 Purple + 2 Blue + 3 Red = 30.
There are 15 purple out of 30.
15/30 = 1/2 probability, which is 50%.
Answer:
Step-by-step explanation:
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.
4 : 5 ( = 9 too little )
8 : 10 ( = 18 just right)
12 : 15 ( = 27 too much)
So per necklace, 8 yellow beads and 10 blue beads would be needed.
I hope this helps :-)
Each friend would have taken a total of 35 rides each.
This can be verified by multiplying 35 by 35 to get 1225.
Walking at 3mph he wouldve walked 15 miles in 5 hours, leaving 133 miles on bike.
133/41=3.24390244hours on the bike
