Question

Gabriel is making a mixture of compost and soil to use for a special plant. He wants his final mixture to be 2 parts compost to 10 parts potting soil. He wants to end up with 6 kilograms of mix. How many kilograms of compost should he use

Answer 1

Think about it in terms of an equation... 2parts + 10parts = 6kg. how much is one "part"?

Answer 2

16?

Answer 3

if one part is 16 kilograms, then: (2)(16)kg + (10)(16)kg = 192kg

Answer 4

solve it like an algebra problem, 2P + 10P = 6, P = ?

Answer 5

I'm lost. 10+6= 16p? Then?

Answer 6

Here's how I would do it:

2P + 10P = 6
12P = 6
12P/12 = 6/12
P = 1/2

so one part is one half of a kilogram

Answer 7

he's using 2 parts compost. figuring out how much compost he's going to use it pretty easy now

Answer 8

so 8?

Answer 9

one part is 0.5kg, so 2 parts is 1kg

Answer 10

and it makes sense if you plug in these numbers in the original questions.... if he uses 1kg compost, and 5kg dirt, he'll end up with 6kg soil
