Why is not 6:8:9/12 = 782 ?

I mean 782 must be multiplied by 12 so it should be 23x = 782*12.

So,
X/2 + 2X/3 + 3X/4 = 782,
23X/12 = 782.
X = 408.

NOW, 1ST PART.
1/2 * (X)= 408/2 = 204.

Why take LCM when we can directly simplify 1/2:2/3:3/4 by cancelling the common factor?

Siva j said:   1 decade ago
Just simple calculation 1/2+2/3+3/4 = 23/12.

23/12 = 782.
1/2 = ?
782*1/2*12/23 = 204.

You just need to multiply every ratio by 12 because it is the lcm of denominators.

1/2 = 50%.

2/3 = 66.67%.

3/4 = 75%.
____________

191.

982 x 50/191 = 204.

Taking lcm for 2, 3, 4 and we got 12. Then the numerators 6, 8, 9 were used.

1/2:2/3:3:4 is written as 6:8:9

how can you explain? plz explain clearly.

It is very simple methods. But it is not. Can solve apply to other method?

1/2+2/3+3/4 = 23/12.
We need first part i.e 1/2.
1/2 * 12/23 * 782 = 204.
