So basically the question just wants you to add fractions so we set up the problem like this
1/2+1/5+1/8=weight of herbs=x (x signifies an unknown number)

so we have to get the bottom numbers the same before we can add them so we have to find the smallest number that they all can multiply into
so
       2=2
       5=5
       8=2*2*2
       so the smallest number that that will go into all three of the numbers is
     2*2*2*5 =40
so the bottom number will be 40
so 1/2 is equal to 20/40
1/5=8/40
1/8=5/40
so 20/40+8/40+5/40=33/40
answer is 33/40 grams
so

8. The expression below is evaluated when x = 9, y = 3,
Reptile [31]

Answer:

64

Step-by-step explanation:

First of all substitute the values to where ever you see their corresponding variables to make them multiply.

x = 9

y = 3

z = 2

so we get

8x as 8(9),

7z as 7(2)

2y as 2(3)

then the it's will be

8(9) - 7(2) + 2(3)

which is

72 - 14 + 6

finally we get

64

Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y
Radda [10]

Answer:

The product will be less than the second factor.

Step-by-step explanation:

Given the expression

\frac{4}{5}\:\times \:1\frac{2}{5}\:=y

solving to determine the product value

y=\:\frac{4}{5}\times \:\:1\frac{2}{5}

  =\frac{4}{5}\times \frac{7}{5}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

  =\frac{4\times \:7}{5\times \:5}

  =\frac{28}{5\times \:5}

  =\frac{28}{25}

As the value of the second factor is:

1\frac{2}{5}=\frac{7}{5}=1.4

And the product value is:

y=\frac{28}{25}=1.12

It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.

i.e. 1.12 < 1.4

Thus, the product will be less than the second factor.
