To divide 249g in the ratio 5:3:4, we first need to find the total number of parts in the ratio:
5 + 3 + 4 = 12
Next, we need to find the value of one part:
249g ÷ 12 = 20.75g
Finally, we can find the amount of each part:
5 parts = 5 × 20.75g = 103.75g
3 parts = 3 × 20.75g = 62.25g
4 parts = 4 × 20.75g = 83g
Therefore, we can divide 249g in the ratio 5:3:4 as 103.75g : 62.25g : 83g.
