Percent and fractions: Ratio and proportion

Male support engineer, brown hair, blue shirt, red tie: I'm calling regarding the problem you were having this morning with your email.

Male, brown hair, white shirt: Our ratio of computers to support engineers is about 150.

Each engineer can look after 150 computers and if we bring on a customer with 300 users, that tells us that we need to hire two more people.

Male hairdresser, black hair, glasses, black shirt: When it comes to colouring, all of it is down to ratio.

Male hairdresser, black hair, glasses, black shirt: We need a whole tube of this colour, that's 50ml of the colour, and I need to mix it with the appropriate releaser which would be 75ml.

And the ratio of the mixing of this colour is 1 to 1.5, so it's important that I mix exactly 75ml up, just so next time we get the exact same colour, again.

Male builder, glasses, yellow jacket, white hard hat: The typical concrete mix just for your standard sort of foundations or something like that, would normally be a six and one.

So that would be six parts of ballast to one part of cement.

So it wouldn't matter if you were mixing up six shovel fulls…

Male: Six cups.

Male builder, glasses, yellow jacket, white hard hat: …or six cups or six teaspoons, it's the same amount.
