Ratios (mathematical)

There are different concrete mixes and the will depend on which mix it is. The material ratio will remain the same whatever the volume is.

The ratio of 5000 to 3000 is 5:3.

103/25

There is no specific ratio for bronze because there are many different bronzes.

For example,

Aluminium bronze contains 92% copper, 8% aluminium.

Phosphor bronze contains 89.75% copper, 10% in and 0.25% phosphorus.

Manganese bronze contains 58.5% copper, 39.2% zinc, 1% Iron, 1% tin, 0.3% manganese.

There is no such thing.

People used the body mass index (BMI), which is a ratio of mass (not weight) to the square of the height. A BMI of 18.5 to 25 kg/m2 is considered normal. Below 18.5 is underweight and above 25 is overweight. Above 30 is obese.

However, the people who promoted this measure appear to have overlooked the very basic fact that muscles are denser than fat. So, two people can have the same height. If one of them is muscular and has a BMI of just over 25 whereas the other carries a lot of fat and has a BMI of 24.5, the first one is fitter, not fatter!

The ratio depends on the compound.

I suspect that the answer is specific gravity but, with only part of the question being visible, it is hard to be sure.

8 out of 10 boys play a sport , 25 out of 30 boys play a sport

The 2014 estimates are 986 women: 1000 men.

12 to 32 has a ration of 3 to 8

It is 15/100 = 3/20.

No, time is a fundamental unit in the SI system (and also the Imperial system) of units..

The ratio of two integers P and Q can be expressed as P : Q or P/Q. In both cases, you may divided P and Q by their greatest common factor so as to express the ratio in its simplest form. Alternatively, you may multiply both by some number so that the first part is 1 or the second part is 1 (both unit ratios), or the second part is 100 (a percentage), or a million (part per million) and so on.

Yes , of course. One-fifth is one divided by five. One and five are both integers, making a fraction (sometimes called a ratio). That's what a rational number means.

5/N, where N is the unspecified number.

The answer to the question depends on what the ratio is between: side length and area, or lengths of base and height, or interior and exterior angles. But since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

It is 33/48. This is also equal to 330/480 or 11/16.

14.99 is a mathematical quantity. It means that same thing in any language - especially those using Indo-Arabic numerals.

It is -33:2 or -33/2.

It is 113/93. You can simplify the ratio of required.
