I'm assuming that when you wrote "(7x/2-5x+3)+(2x/2+4x-6)," you actually meant "<span>(7x^2-5x+3)+(2x^2+4x-6).  Correct me if I'm wrong here.

</span><span>+(7x^2-5x+3)
</span><span>+(2x/2+4x-6)
-------------------
=9x^2 - x - 3 (answer) </span>

How to estimate 5 2/11- 3 2/18
Nimfa-mama [501]

Answer:  The estimated value is:  " 2.1 " .

__________________________________

Step-by-step explanation:

__________________________________

We are asked to "estimate" :

 5 2/11  -  3/ 2/18 ;

 Note:  Consider:  " 5 2/11 " ;  

 Note that:  "2/11" is close to:  "2/10" ; which can be expressed as a decimal value:  "0.2 " ;

So, consider this value:  "5 2/11 ";  as estimated:  " 5.2 " .

Now, consider:  " 3  2/18 " ;

Note that :  "2/18" can easily be reduced to:  "1/9 ";

               Since:  "(2/18)" = "(2÷2) / (18÷2) " =  "1/9 " ;

Note that "1/9" is close to "1/10" ; which can be expressed as a decimal value:  "0.1 ".

 So, consider:  "3 2/18 " ; as estimated:  " 3.1 " .

__________________________________

So:  To estimate:  " 5 2/11  -  3 2/18 " ;

__________________________________

Use the following:  "5.2  - 3.1 " ;

__________________________________

    5.2

 -  3. 1

__________________________________

  " 2.1 "

___________________________________

The estimated value is:  " 2.1 " .

Hope this is helpful to you!
