Answer:
28 grams
Step-by-step explanation:
1 cup is 8 grams of fiber, since a half a cup is 4 you times it by 2
then 8x3 because you're multiplying the fiber of one cup by 3. which equals 24, but you still have a half of cup of oats left. and since 4 grams equal a half a cup you just simply add 4 onto 24 which equals 28
Well 106 divided by 7 is 15 so 15 times 7 is 106
Answer:

Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example

and

ARE Conjugates.
The conjugate of

is

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be

We can apply the difference of squares for the denominator.

So our denominator will be

So our rationalized fraction will be

(3a) - (8a) = -5a
2b + b = 3b
-5a + 3b
