Question

Gabriel is making a mixture of compost and soil to use for a special plant. He wants his final mix to be 2 parts compost to 8 parts potting soil. He wants to end up with 12 kilograms of mix.

Answer 1

2 parts out of 12 are compost, 10 parts out of 12 are potting soil

(2/12) * 10 grams of compost should be used

((2/12)*10) grams * 1 kg/1000 grams = 0.0016 kgs
