It is one of two kinds of unit ratios (the other has numerator = 1).
cross product
When you multiply the numerator of one ratio by the denominator of another ratio in an equation, you are using the cross-multiplication method to solve the proportion. This technique allows you to set the products of the extremes equal to the products of the means, facilitating the solution of the unknown variable in the proportion.
It does not change. If the numerator changes then, unless the denominator changes in the same proportion, the fraction is no longer the same.
The denominator of 12 is 1.
In a percent proportion, one of the ratios has a denominator of 100 because percent means "per hundred." This standardization allows for easy comparison and calculation of parts relative to a whole. By using 100 as the denominator, it simplifies finding percentages, as it directly represents the fraction of the whole in terms of hundreds. This makes it intuitive to understand and apply in various mathematical and real-world contexts.
denominator
A percent is a proportion based on a denominator of 100.
Proportion
A percent is a proportion with the denominator equalling 100.
Proper fraction - A proper fraction is a fraction where the numerator (the top number) is less that the denominator (the bottom number). Proportion - An equation stating that two ratios are equivalent is called a proportion.
cross product
You get the same answer both times.
When you multiply the numerator of one ratio by the denominator of another ratio in an equation, you are using the cross-multiplication method to solve the proportion. This technique allows you to set the products of the extremes equal to the products of the means, facilitating the solution of the unknown variable in the proportion.
If that's 127, the denominator is 1. If that's 1/27, the denominator is 27.
It does not change. If the numerator changes then, unless the denominator changes in the same proportion, the fraction is no longer the same.
1 any whole number has a denominator of 1
The denominator of 12 is 1.
