Ratios (mathematical)

15/1 and 150/10 are two such.

It is called the specific gravity.

It is (or should be) given by the key.

the ratio of the radious

There are 3 ways. 30/56, 30 to 56, and 30 : 56.

The current reserve ratio for net transaction accounts totaling more than $43.9 Million is 10%.

It is 225/100 or 9/4

/ both by 16 to get 7:1.

It is: 1 to 2

Some prisons over 300 to 1. Imagine that?

Divide one of them by the other one.

They are equivalent ratios.

Quite possibly, "conversion factors".

As a ratio it would be 20:1

stoichiometry

25 is an integer and not a fraction. However, it can be expressed in rational form as 25/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.

34 : 124 = 68 : 248

wat is the ratio of a and b

482/1282 = 241/641.

There are several means by which the compression ratio of an engine might be reduced although all involve extensive mechanical rework to accomplish.

1) Remove the heads from the motors and grind the compression chambers of the head(s) to make the area larger.

2) Install replacement pistons that have a different shaped piston top (usually a larger "dished" area)

The poisson ration of uncompressed polyurethane is 0.5; the poisson ration of polyurethane under compression is 0.39. Reference: "Material behaviour in plane Polyurethane - Polyurethane impact with velocities from 10 to 400 m/sec." Published at J. Phys IV France 7 (1997)

Archimedes determined that pi was between

31/7 = 3.1429

and

310/71 = 3.1408.

To four decimal places, the true value is 3.1416

Something that is 0.9" by 0.9" in size.

It is 5 to 9
