Question

A cereal mixture contains almond, wheat and corn in the ratio of 3:5:7. What amount of this mixture contains 9 kg of almond?

Answer 1

Almond is 3 out of

`3+5 +7 =15 \: parts`

`(3)/(15) x = 9kg`

`x = 9 * (15)/(3) = 45 \: lbs \: of \: cereal`

Answer 2

45 Kg of the of this mixture contains 9 kg of almond

Explanation:

Given:

The ratio of almond, wheat and corn = 3:5:7.

To Find:

Amount of this mixture contains 9 kg of almond =?

Solution:

The total of the fraction = 3+5+7 = 15

Let the total amount of the mixture be X, then

Then

`\frac{ \text{ratio of the almond in the mixture}}{\text{total ratio}} * X = 9`

`(3)/(15) * X = 9`

`X = 9 * (15)/(3)`

`X = 9 * 5`

X = 45
