This topic is p*ssing me off! How can I learn ratios? Any useful YouTube videos?

For example, this question:

I have 3 types of shapes: triangle, square, or circle in the ratio 3: 6: 1. The triangles are either red or blue. The ratio of red triangles to blue triangles is 4:5. Given that I have 12 red triangles, how many circles are there?

It's so bloody confusing!!

Do the same to 5. This will in turn yield the number of blue triangles. So what is the total number of triangles??

Then the ratio (triangle : square : circle) which is 3 : 6 : 1 means the ratio of triangles to squares is 3 : 1.

I.e. for every ONE circle, we have THREE triangles... so since you have the number of triangles, just think about how you can deduce the number of circles here.

I usually start ratios with:

I have 4 sweets and agree to share (some!) with username4426374 in the ratio (me) 3 : 1 (you).

How many do we each get? I get 3 and you get 1. So I then acquire more sweets and agree to share those in the same ratio. If I now have 20, how many do you get? We share each four out as 1 to me, 3 to you..... i.e. four at a time. How many 4s in 20? 5? So we do this 5 times and you get 1x5 and I get 3x5 (check: do our two shares add up to 20?). This is the basis of ratios. Any help?

So let's go with those as 12+15=27 triangles.

Put the 27 into the 31 ratio and.....
