Answer 2
Answer: She would use 11 and 1/4 milliliters to make the perfume. 3+3+3=9. 3/4+3/4+3/4= 2 and 1/4. 9+2 and 1/4= 11 and 1/4 milliliters:)

What is 7a - 3 = 3 + 6a

Answers

Firstly, you add 3 to both sides (as you've got to eliminate the -3), and this gives you;
7a=6+6a.
Then in order to get a alone, you need to subtract 6a from the right hand side (in order to counter balance) and this gives you;
1a=6
Therefore, a is equal to 6

What is 14% of 56
Please explain

Answers

14% is 14/100 or 0.14

56 * 14 / 100 = 7.84


14 is the percentage
100 is ALWAYS the whole percent.
So 56 is the whole because the word "of" is the word that shows its a whole.
We need to find the part not the whole because the whole is given to us.
So if we visualize this it would look like....
x/56 = 14/100 ( do this in the straight real way)
x is the answer we need to find.
So we can cross multiply. 
56 × 14 equals 784
We divide the 784 to 100 to find the part.
So 784 / 100 equals... 7.84
So x = 7.84
BTW (BY THE WAY) x is the answer also the part.
