How is showing fractions on a number line like showing fractions using models?

Showing fractions can be expressed in model and number line.

Using a model, you need to show the parts.

Using a number line, the line starts from 0 to the number of the denominator.

Both model and number line use the value of the numerator and denominator. What makes them different is how they are presented. Model can easily be understood compared to number line.

* Showing fractions can be expressed in model and number line.

* Using a model, you have to draw the number of parts (denominator) and shade the number of parts (numerator).

* Using a number line, the line starts from 0 to the number of the denominator. You put a marker to the number that is the same as the numerator.

* Both model and number line use the value of the numerator and denominator. What makes them different is how they are presented. Model can easily be understood compared to number line.

HERE ARE SOME EXPLANATION

Hope this helps :)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
