Margo lists the sizes, inches, of set of screws: 9/64, 5/32, 1/16, 1/8. she reasons that because the denominators are in order from greatest to least, the list is in order from least to greatest. is margo correct? why or why not ?

I think she is incorrect she need to change all the fractions to the same denominators

Step-by-step explanation:

We are going to change all the fractions to 64

9/64 stays the same

5/32 multiply 2    then 10/64

1/16 multiply by 4 then 4/64

1/8 multiply by 8  then 8/64

Now we can order then

5/32 > 9/64 > 1/8 > 1/16 This is the right order

She was wrong.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
