1) I need to split 4.8kg into the ratio of 1:5
2) 2 people are eating apples, between them they eat 162 cherries in the ratio of 4:5 ( i need to work out who is the winner and how many they ate) any ideas as to how I can work these out, please.

do 4.8/6 = X (calculate it) then ratio 1:5 as X*1 : X*5

add both 4 and 5 then divide 162 by the sum then multiply the 162/9 by 4 and 5

Add the two sides of the ratio together
Next divide the items by that number
Times that result by each side of the ratio respectively

E.g. If you had 30 pens in a ratio of 2:4 then it would be:
30 / (2+4) = 5
2 x 5 = 10 and 4 x 5 = 20

I know for the first one you add the 1 and the 5 together which gives you 6 parts in total.

Then you divide the 4.8 by 6 to give you one part so 4.6kg divided by 6 is 800g.

Then you plug the numbers back into the ratio
1 times 800g =
5 times 800g =

Then for the second question about the cherries do the same thing. Add the 4 and the 5 together to give you 9. Then divide the amount of cherries which is 162 by 9 and so on
