Q: The unit rate is a special type of ratio in which the two separate measurements are compared and expressed as a quantity of one.  A "ratio" is any comparison of two numerical measurements. Each measurement is called a "term." A "rate" is a ratio in which the two terms are measured in different units. All rates are ratios, but not all rations are rates. A "unit rate" is a rate in which the second term equals "1." When calculating a unit rate, you need to determine how much of the first term exists for every one unit of the second term. The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term.  Common examples include: speed (miles/kilometers per hour), unit price (cost per item), and wage (earnings per hour/week).  If you aren't sure about whether or not you're being asked for the unit rate, look for the word "per" somewhere in the description. Some unit rate problems won't include "per," but many do.  Example: A certain bakery can bake 40 loaves of bread in an 8 hour work day. How many loaves of bread can that same bakery make in one hour? In other words, how many loaves of bread are typically baked per hour? The first term in the problem—the amount you are trying to calculate per unit—will become the numerator (top number). The second term—the unit—will become the denominator (bottom number).  Example: You must calculate loaves of bread per unit of time (in this case, the unit of time is an hour). The total loaves of bread will become the numerator, and the total hours will become the denominator, giving you: 40 loaves / 8 hours To find the unit rate, simply solve the newly written division problem. Doing so will reduce the denominator to "1."  Example: Divide the total number of loaves by the total number of hours: 40 loaves / 8 hours = 5 loaves/hours You should now have your final answer ready.  Make sure that you include both units in your answer. You can either separate the units with the fraction sign (/) or with the word "per."  Example: This bakery can bake 5 loaves/hour. Alternatively, you could write, "This bakery can bake 5 loaves per hour.”
A: Understand unit rate. Look at the data. Rewrite the data as a division problem. Divide both values by the denominator. Write the solution.

Q: Allow it to burn until a small melted wax puddle forms around the flame area. The candle should lack fragrance, else it may overpower or mix poorly with the scent you're adding. Avoid placing the oil anywhere near the actual flame. Top up as often as needed.
A: Light a fragrance-free candle. Use a pipette or dropper to add a single drop of essential into the melted wax puddle. Expect the scent to begin wafting out as the candle continues to burn.

Q: You may be uncomfortable perpetuating the Santa story or feel discomfort about lying to your child, and those are legitimate concerns shared by many. On the other hand, you may want your child to believe in something whimsical and magical, like Santa. How to deal with the Santa Claus story is a personal decision that can only be made by your family. Remember, though, that even if you do not share the Santa story in your own family, your child might still come to you with tricky questions about Santa. Perhaps they heard something at school or they have thought about the Santa story and it doesn't completely make sense. Acknowledge the question and praise them for their critical thinking. This is actually a positive developmental step. Determining their reason for asking will help you figure out the best way to proceed.  You might give this question some thought before it ever comes up, so that you are not caught completely off guard. This will help you respond more thoughtfully and slowly, rather than be reactionary. Ask your child very plainly, "Why do you ask?" or "Where is this question coming from?". Just because the child is asking questions doesn't necessarily mean that they are emotionally ready to believe the truth. They may just be curiously probing. Asking what your child believes will give you an idea of where they are emotionally and cognitively. If your child indicates that they still believe in Santa, despite any outside doubts, it's likely not time to tell them the truth yet. Respond to your child's question with a simple, "Well, what do you believe?" This allows them to reflect on what they think and whether or not they believe in Santa Claus. When your child answers your question about what they believe, they will tell you that they don't think Santa is real, or that they do but that they have questions.  This answer should guide how you proceed and you can either tell them the truth about Santa or let them continue to believe. They may also say that they do believe the story of Santa Claus, but are confused about something specific in the Santa story, such as how he gets around the world in one night, or fits all of the presents in one bag.  Just reiterate whatever you've already told them and answer questions as best as you can.
A:
Consider your own feelings. Find out what inspired the question. Ask what the child believes. Follow your child's lead.
