A class consists of 16 kids, 6 boys and 10 girls.
Emily questioned all the students and discovered that
8 out of 10 girls prefer valentines day over birthdays, but only 2 out of 6 boys prefer valentines day over birthdays.
What is the ratio of children in the class that prefer valentines day over birthdays.

Impossible, as the numbers only add up to 45. Unless the question was meant to include the number 10 as well?

Hello, Nancy -

If you think you will ever need to convert metric measurement to
"English" measurement (used in the USA), this is a great web site (for all kinds of conversions):
http://www.metric-conversions.org/volume-conversion.htm

This is the link to the home page for conversions:
http://www.metric-conversions.org/

I suggest you save that web page address to your Favorites / Bookmarks.

Using the conversions calculator for milliliters to U.S. fluid ounces, this is the result:
50 ml = 1.690701 U.S. fluid ounces
This is the result for U.K. fluid ounces:
50 ml = 1.759754 U.K. fluid ounces

I assume your question has to do with liquid perfume.

That's it.

A long, fairly thorough way that shows the thinking behind it (usually considerably shorthanded in practice):
1) Rewrite the (negative-signed) elements of the equation so that their signs are clearly attached to them and cannot be confused with operations [you could also add the + in front of the positive-signed elements as well] -->
2.93 + 19j = -j + -5.82 + -11.25
2) Add j to both sides to consolidate all the j's on the same side of the equation [adding the same thing to both sides doesn't change the balance/value of the equation] --> 2.93 + 19j +j = +j +-j + -5.82 + -11.25 --> 2.93 + 20j = -5.82 + -11.25
3) Subtract 2.93 from both sides so that the j's are all by themselves on one side of the equation --> 2.93 + -2.93 + 20j = -5.82 + -11.25 + -2.93 --> 20j = -5.82 + -11.25 + -2.93
4) Add up the numbers on the right and rewrite the equation --> 20j = -20
5) Solve for j by dividing both sides by 20 [j's coefficient] --> j = -1
6) Test the answer in the left side of the equation --> 2.93 + 19(-1) --> 2.93 + -19 --> -16.07
7) Test the answer in the right side of the equation --> -(-1) + -5.82 + -11.25 --> 1 + -5.82 + -11.25 --> -16.07
8) Compare and validate: -16.07 = -16.07
