Answer:
240g in the ratio of 5:3:4
So we need to divide it evenly.
First add up all the ratios.
5+3+4= 12
Now divide 240 by the sum.
240/ 12 = 20
Now you multiply that into each ratio.
5*20 = 100
3*20 = 60
4*20 = 80
Now put it back in the ratio with the new numbers int he exact order as before.
Final Answer: 100 : 60 : 80
Check:
You can check by adding them all up to see if they all go into 240 OR you can divide them each by the number originaly given and you should get 20.
100 + 60 + 80 = 240
100 / 5 = 20
60/3 = 20
80/4 = 20
