The y's are -3 and 2, while the x's are 9 and -1.

(-3-2)/(9-(-1))=-5/10=

A chicken salad recipe calls for 1 8

NARA [144]

Answer: $1.0625\ pounds$ or $\frac{17}{16}\ pounds$

Step-by-step explanation:

The complete exercise is: "A chicken salad recipe calls for $\frac{1}{8}$ pound of chicken per serving . How many pounds of chicken are needed to make $8\frac{1}{2}$ serving".

You can convert the Mixed number to a Decimal number. Divide the numerator 1 by the denominator 2 and then add the quotient to the Whole number. Then, you get:

$8+0.5=8.5$

Now divide the numerator 1 by the denominator 8 to write the fraction to a Decimal number. Then:

$\frac{1}{8}= 0.125$

Let be "x" the amount of pounds are needed to make $8\frac{1}{2}$ serving.

Then, you can set up the following proportion:

$\frac{1}{0.125}=\frac{8.5}{x}$

Solving for "x", you get:

$\frac{1}{0.125}=\frac{8.5}{x}\\\\x(\frac{1}{0.125})=8.5\\\\x=8.5*0.125\\\\x=1.0625$

or $\frac{17}{16}\ pounds$
