The Concept of a Ratio
Hello :)
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
= 0.6
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?
Thanks :)

we just divide:

ratios can be expressed as rational functions (or should i say numbers? Note: "rational function/number" is just a fancy word for fraction)

so 3:5 is the same as 3/5 = 0.6
