Question

Divide 75 liters in the ratio 12 8 5

Answer 1

36 : 24 : 15

Explanation:

sum the parts of the ratio, 12 + 8 + 5 = 25 parts

Divide the quantity by 25 to find the value of one part of the ratio

75 l ÷ 25 = 3 l , then

12 parts = 12 × 3 = 36 l

8 parts = 8 × 3 = 24 l

5 parts = 5 × 3 = 15 l

Answer 2

According to the question,

`12x + 8x + 5x = 75`

_____________________

`12x + 8x + 5x = 75`

`25x = 75`

`x = (75)/(25)`

`x = 3`

Now,

`12x = 36`

`8x = 24`

`3x = 15`

So,

75 in the ratio of 12 : 8 : 5 is

36, 24 and 15
