Question

1)When solving problems, sometimes a negative answer makes sense, and sometimes it really doesn't. Give one example of a real life problem that could have a negative answer and one that could not.

2)You need to explain equivalent fractions to a child learning it for the first time. Go for it!

3)Find an example of decimals, and computation of decimals, in recent news or in your daily life. Remember that money counts. Explain the source, and show at least one computation that you performed.

4)Explain equivalent fractions to a child learning it for the first time. What fractions are equivalent to 3/5? Why and what are they good for?

5)Any fraction can be expressed as a decimal, and vice versa. Which do you prefer, and why? Give one example of a fraction which you can make easier to understand by converting to a decimal.

PLEASE TYPED!! THANK YOU

Answer 1

1. Sometimes negative answers makes sense and sometimes it doesn't. For example if we are calculating temperature for some problem and its answer come -2degree celsius here -2 make sense because temperature -2degree celsius does exist. But if we are calulating like profit and its comes -700$ then negative 700$ does not make sense because there is no such money exist in real life. So we have to understand that here negative 700$ profit means the loss of +700$ .

2. Equivalent fractions are those that have different numerators and denominators but both represent the same number. For example 7/10 and 14/20 these fractions have different numertors and denominators but both represent the same number . So these type of fractions are called equivalent fractions.

3. Daily temperature can also be used as a example of decimal. Yesterdays temperature was 36.2 degree celsius. And todays temprature rise 2.4 degree from the yesterday it means,

Todays temp= yesterdays temp+ 2.4

Todays Temp= 36.2+2.4= 38.6

So todays temperature is 38.6degree celsius

4.Equivalent fractions are those which have different numerators and denominators but they represent the same number. For example 3/5 and 6/10 have different numertors and denominators but both fraction represent the same number. Fractions are useful for representing the proportion . Fractions tells u how much proportion is needed of the whole for work. For example for making 1 cup of tea u need just 1/3 of the full cup of water.

5. Any fraction can be written in the form of decimal. But we uses fraction where we have to use the proportion of the whole of something and we use decimal when we need a precise number for some calculation or to represent something precisely.
