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
