This isn't really a urgent question, but i'd just like to ask something, that i have forgotten! I'v got a Maths Exam later today and i'm doing a bit of revision.
okay here it is:
600 mL to 1000 mL = 600 : 1000
= 3 : 5
i'v forgotten how to to the numbers in bold. Like how do we simplify it? How do we narrow the result in red, to the bold numbers?
