One batch of pancakes calls for 3/8 cup of wheat flour and 4/8 cups of white flour . how much flour is needed for three batches of pancakes ?

1  1/8 cups of wheat flour

1  4/8 or 1  1/2 cups of white flour

if you add both cups together then 2  5/8 cups of flour

Step-by-step explanation:

3*3=9 so 9/8 -> 1  1/8 cups of wheat flour

4*3= 12 so 12/8 -> 1  4/8 or 1  1/2 cups of white flour

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
