30 ounces = how many pounds and ounces

    " 1 lb ,  14 oz. " .

_________________________________________________

Step-by-step explanation:

_________________________________________________

Note the exact conversion:    " 16 oz.  =   1 lb.  " .

→  {that is:  " 16 ounces  =  1 pound " .}.

_________________________________________________

  30 oz. * ( 1 lb / 16 oz). =    lbs. ;

                                      = (30/2) / (16/2)   lbs.

                                      =  (15 / 8) lbs.  ;

_________________________________________________

       1

8 ┌ 15

    -  8                            

        7  ;              

______________________

The answer is equal to:  " 1  7/8  lbs. " .  

           →   (1 lb)  + (7/8) (lb).  ;

______________________

 →  (7/8) lb.   =  how many "oz." ??

_______________________

Note the exact conversion:   " 1 lb.   =   16 oz.  " .

_______________________

 →   *  ;

                    =    oz.   ;

 →  The "8" cancels to a "1" ; and the "16" cancels to a "2" ;

                   →  {since:  " {16 ÷ 8 = 2 } " ;  

             and:   {since:  " {8 ÷ 8 = 1 } " .

_______________________________________________

 →  So we can rewrite as:  

_______________________________________________                  

                  →    oz. ;

                         =  { 7  *  2 }  oz.  ;

                         =   14  oz.

_______________________________________________

→  So:        

_______________________________________________  

 →   " 30 oz. "  =  " (1 lb)  + (7/8) lb.  "  ;

                        =  "  1 lb. + 14 oz. "  ;

                        =  " 1 lb ,  14 oz. " .

_______________________________________________

        →  The answer is:  " 1 lb ,  14 oz. " .

_______________________________________________

Let us check our

  →   Does:     " 1 lb.  +   14 oz. = ?  30 oz. ? " ;

_______________________________________________

Note the exact conversion:  " 1 lb.  =  16 oz. " .

_______________________________________________

  →   Does:  " 16 oz.   +   14 oz.   =  ?   30 oz. ??  " ;

_______________________________________________

  ₁

  16 oz            

+ 14 oz            

  30  oz.

_______________________________________________

→   Does:   " 30 oz.  = ?  30 oz. ? "  ??? ;  →   Yes!
