Ok, 10 + 2 = 12
Now look at the two lines below and compare them.

2 parts compost + 10 parts soil = 12 parts total
x kg     compost +   y kg     soil = 12 kg total

mathstudent55 · Answer

I'm not trying to give you hard time. In fact, I'm trying to help you; that's why I answered your question. I just don't understand how you can have seen a subtraction sign four times instead of an addition sign.

mathstudent55 · Answer

Exactly. 2 kg of compost + 10 kg of soil = 12 kg total mix
You got it right.

rayray1234 · Answer

On my screen it looks like a subtraction sign i dont know why .. So the answer to all of this is 2 ?

mathstudent55 · Answer

The answer is 2 kg of compost and 10 kg of soil.
Remember the question was how many kg of compost and how many kg of soil do you need to make 12 kg of mix.

mathstudent55 · Answer

No, you are correct. The question is only how many kg of compost, so the answer is:
2 kg of compost.
