A certain fraction is greater than 2. The denominator is 8. What must be true about the numerator?
Volgvan

Answer:

The numerator must be greater than 16

Step-by-step explanation:

We are told that a certain fraction is greater than 2. Thus, if the numerator and denominator are x and y respectively, then we have;

x/y > 2

We are further told that the denominator is 8.

Thus;

x/8 > 2

Multiply both sides by 8 to give;

x > 16

Thus,the numerator must be greater than 16.

Which package has a better price a 10 pack of 2.1 ounce bars which costs $15.37 or a 12 pack of 1.4 ounce bars which cause $15.3
jasenka [17]
<span>Find which is a better package between the 2
 10 pack of 2.1 ounce bar = costs 15.37 dollars
=> 2.1 x 20 = 21 there are a total of 21 ounce of bar
=> 21 / 15.37
=> 1.366 dollars / ounce

12 pack of 1.4 ounce bars = costs 15.35
=> 1.4 x 12 = 16.8, there are 1a total of 6.8 ounces of bar
=> 16.8 / 15.35
=> 1.094 dollars / ounce

Thus the second choice is the better package between the two. The 12 pack of 1.4 ounce bars.</span>
