Six cells phones weigh 46.2 ounces. fourteen cell phones weigh 107.8 ounces. does this represent a proportional relationship? explain. if so state the constant of proportionality

The answer to your question is yes, there is a proportional relationship

Step-by-step explanation:

Data

6 cell phones weight 46.2 ounces

14 cell phones weight 107.8 ounces

Process

1.- Divide the weight by their respective number of cell phones

    a)    46.2 / 6 = 7.7

    b)   107.8 / 6 = 7.7

2.- Conclude. It is a direct proportion because the result of both divisions is equal. That means that if the number of cell phones increases, the weight will be higher.

  The constant of proportionality is 7.7.  

3.- Equation for the weight of any number of cell phones

           Weight = 7.7 x number of cell phones

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
