tigry1 [53]
The answer is:  " 270 minutes " . 
__________________________________________________________
        →  There are "270 minutes" in "4 hours and 30 minutes" .
__________________________________________________________
Explanation:
__________________________________________________________
Method 1):
__________________________________________________________
  Note:  60 minutes = 1 hour (exactly); 

30 minutes =   ?   hr ? ; 

→  (30 minutes) * (1 hr/ 60 minutes) ;

=
(30/60) hr = (3/6) hr  = (3÷3)/(6÷3) hr ;

=
" \frac{1}{2} hr " ;  

or; write as:  " 0.5 hr " .        
_________________________________________________________

So  "4 hours & 30 minutes" = 4 hours + 0.5 hours = 4.5 hours.

→   4.5 hours  =   ?  minutes ; 

The answer is:  " 270 minutes" .  4.5 hours * \frac{60 min}{1 hr}  ; 

       =  (4.5 * 60) minutes  =  " 270 minutes " .

→  The answer is:  " 270 minutes ".
___________________________________________________________
Method 2)
 
___________________________________________________________

    "4 hours and 30 minutes"  = <u>  ?  </u> minutes " . 
___________________________________________________________

→  " 4 hours   =  <u>  ?  </u> minutes " ; 

→   4 hr . * \frac{60 min}{1 hr}  =  (4 * 60) minutes  =  240 min. ; 

→  There are " 240 minutes in 4 hours" .

→  To find the number of "minutes" in "4 hours and 30 minutes" ;

→  we takes the number of minutes in 4 hours—which is "240 minutes"—and add "30 minutes" to that number; as follows:
   
           →  " 240 minutes + 30 minutes " ; 

to get:   " 270 minutes " . 
_______________________________________________________
 
      →  There are  "270 minutes"  in  "4 hours and 30 minutes" .
_______________________________________________________

The answer is:  
" 270 minutes " .

Holland added three decimals that made a sum of 2. One of the decimals was 0.34. What are two other decimals Holland could have
ddd [48]
From this question, you can conclude:
1. There are 3 decimal
2. Decimal1 + decimal2+ decimal3= 2
3. The first decimal is 0.34

If you insert the 3rd into 2nd equation, it will become:
0.34+ decimal2+ decimal3= 2
decimal2+ decimal3= 2-0.34
decimal2+ decimal3= 1.56

If there are no rules regarding the second and third decimal, then you can use this both
1.01 + 0.55
0.78 + 0.78
