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!

A student has a 2% salt water solution and a 7% salt water solution. To best imitate salt water at a local beach, he needs 1 lit
FromTheMoon [43]

Let

x-------> the amount of 2\% solution

y--------> the amount of 7\% solution

we know that

2\%=0.02\\7\%=0.07\\3.5\%=0.035

so

x+y=1

y=1-x -------> equation A

0.02x+0.07y=0.035 -------> equation B

substitute equation A in equation B

0.02x+0.07(1-x)=0.035

0.02x+0.07-0.07x=0.035

0.05x=0.035

x=0.7\ liters

find the value of y

y=1-x

y=1-0.7=0.3\ liters

therefore

The student need 0.7\ liters of 2\% solution and 0.3\ liters of 7\% solution

<u>the answer is</u>

A) The percent values were written incorrectly in the equation

B) The amount of 7% solution should be written as 1 – x, not x – 1.
