In order to know what is the reasonable amount of tile for Mandana to order, you have to divide the choices with the area of the floor and deduct with 1 and multiply by 100. You have to assess if the answer you will get will fall between 15% and 20% which is the goal of Mandana.

<span>a.       </span>131/116.9 = (1.1206 – 1) x 100 = 12.06%, this does not fall between 15% and 20%

<span>b.      </span>138/116.9 = (1.1805 – 1) x 100 = 18.05%, this fall between 15% and 20%

<span>c.       </span>133/116.9 = (1.1377 – 1) x 100 = 13.77%, this does not fall between 15% and 20%

<span>d.      </span>141/116.9 = (1.2062 – 1) x 100 = 20.62%, this does not fall between 15% and 20%

Therefore, the reasonable amount of tile for Madana to order that is between 15% and 20% extra of the materials is 138 square feet.

Explain how showing fractions with models and a number line are alike and different?
Otrada [13]
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.
