Question #10:

To find what fraction of an onion is used per serving, divide the total amount of onion by the total number servings.

1/2 ÷ 6 = 1/12

Therefore, 1/12 of an onion was used per serving.

Question #12:

1/2 of 3/4 means that we multiply 1/2 to 3/4.

3/4 * 1/2 → 3/8

3/4 of 1/2 means we multiply 3/4 to 1/2.

1/2 * 3/4 → 3/8

Therefore, both expressions are similar.

Best of Luck!

Step-by-step explanation:

10. Take the amount of onion and divide by the number of servings

1/2 ÷ 6

Copy dot flip

1/2 * 1/6

1/12

There is 1/12 of an onion in each serving

12.  1/2 * 3/4 = 3/8

The first is 3/4 of 1/2    The second is 1/2 of 3/4

They are equal

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
