Ratios (mathematical)

It varies depending on the model

Count the turns ratio of the windings. The voltage ratio is equal to the turns ratio. The current ratio is equal to the inverse of the turns ratio.

For instance, a power transformer with a 10:1 turn ratio (primary to secondary) running on 120V will produce 12V. If it consumes 1 ampere from the input, it will provide 10 amperes to the output.

You can simply 27 over 72 by taking the greatest common factor- 9- and dividing them both by that number. 27/9=3, 72/9=8. So, you can simplify 27/72 to 3/8.

The 2014 estimate is 1.014 men per woman.

About 97% of the earth's water is saltwater, the the remaining 3% is freshwater.

The ratio of H2SO4 to WHAT!

The ratio of hydrogen to WHAT!

I have read that 400,000,000 people own I phones. So out of 7 billion people in the world, about 6% own them.

The ratio varies, but most studies place it at around 20 to 1 (20 straight people for every 1 gay person)

This is because the average of the ratios does not take account of the sizes of the numbers in the ratios.

its about 75 men for 100 women

A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.

Yes because 73*3 = 219

1 mile ≈ 1.609344 kilometers

1 kilometer ≈ 0.621371192 mi

The ratio is approx 268 to 1000.
