Luis and his family flew 51487 miles last summer while on vacation rounded to the nearest thousand how many miles did they fly
ludmilkaskok [199]
In the given mathematical value of 51, 487 to round off this number to the nearest thousand, we can elaborate the number values using the expanded form to clearly see the order position: <span><span>1. </span><span> 50, 000 = ten thousands</span></span> <span><span>2. </span><span> 1, 000 = thousands</span></span> <span><span>3. </span><span> 400 = hundreds</span></span> <span><span>4. </span><span> 80 = tens</span></span> <span><span>5. </span><span> 7 = ones</span></span> Now we can observe the numerical value of 51, 487 than 1, 000 is the number in which belongs to the thousands’ position hence since the nearest number is 400 the value will be 51, 000.

___________________________________________
The formula/equation for the Area of a rectangle:

</span>                       w =  ⅓ in;
___________________________
Find the area;  in a "fraction value" ;
_______________________________
   A = L * w    ;

       and solve for "A" (area) in the "form of a fraction:
__________________________________________________

A   = (2/15) in  *  (1/3)  in ;
 
→ A    = [(2*1) / (5*3)] *  in * in ; 
______________________________________________________
→  Answer:  The area is:  " \frac{2}{15}   in² " .
                                          
                                             {that is, "(2/15) in² " .}.
