It takes 1/3 cups of powered punch mix to make 2/3 gallons of punch. If the recipe is for 1 gallon of punch, how much punch is n

podryga [215]

$\dfrac{1}{8}$

Step-by-step explanation:

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Number of powered punch mix cups required to make $\frac{2}{3}$ gallons of punch is $\frac{1}{3}$

Number of powered punch mix cups required to make $\frac{2}{3}$ gallons of punch is $\frac{3}{2}\times$ $\frac{1}{3}$ = $\frac{1}{2}$

Since the recipe is for $1$ gallon,

$\frac{1}{2}$ powered punch mix cups are required to make the complete recipe.

$\frac{1}{4} \times \frac{1}{2}$ powered punch mix cups are required to make $\frac{1}{4}$ recipe.

So, $\frac{1}{8}$ cups of powered punch mix cups are required to make $\frac{1}{4}$ recipe.

Genrish500 [490]

Answer:

Mean score=120

Step-by-step explanation:

Areas of a triangle add upto 180degrees (63+78+x=180) 141+x= (x=180-141) x=39
Areas on a straight line add upto 180degrees

180-78=102

180-63=117

180-39=141

102+117+141=360
Mean=360/3 =120
