Describe what you can do if you make a wrong decision?
Summarize why it is important to think about decisions you make afterward?

Answers

Answer:

If you make a wrong decision, something bad could happen or something wrong. For example, if someone says, "Put your hands up" and they are pointing a gun at you and someone else, you either put your hands up or you or the other person may get shot. I believe it is important to think about your decisions before and afterward just to know if you choose the correct one. For example, if you were given to choose between a Resees candy or a Snicker bar, which one would you choose?  You may choose the Resees candy but once you eat it, it may taste horrible and you may not like it.

Explanation:

Hope I helped!

If one makes wrong decisions, then just accept responsibility, realize, and learn from that mistake.

What is decision making?

Determining a decision, acquiring data, and weighing potential solutions are all steps in the decision-making process.

You can make more careful, intelligent decisions by organizing pertinent information and outlining alternatives by following a step-by-step decision-making process.

Making decisions is crucial since it allows you to select from a variety of possibilities. It is important to gather all relevant information and consider the advantages and disadvantages of it before making a decision.

If you choose poorly, you should take the following actions:

Accept your feelings.Then, pay attention to the unvarnished realities.Don't allow the poor choice rule your life.Give yourself a break.Recognize your regret.If regret consumes you, try cultivating thankfulness.

It is important to think about decisions you make afterward to make sure you you made the right decision.

Thus, this way, one can do if made a wrong decision.

Answer:

Ture

Explanation:

Answer:

When subtracting fractions you only subtract the numerators. So False

Explanation:

In order to subtract fractions you have to find a common denominator between the fractions you are subtracting.

Example:

3/4 - 1/2  I have to find the common denominator which is 4.

So 3/4 satys the same but 1/2 turns into 2/4
