1)  

 Simplify   :   53 + 512 + 1424

Answer: 83


SOLUTION 1 :

=     53 + 512 + 1424  

LCM of 3 12 .24 is  24

=  [(5x8) +(5x2) + (14x1)] / 24

= (40+10+14)24

 = (64)24

 = 83

 



2)  

 Simplify   :   33 + 412 + 1024

Answer: 74


SOLUTION 1 :

=     33 + 412 + 1024  

LCM of 3 12 .24 is  24

=  [(3x8) +(4x2) + (10x1)] / 24

= (24+8+10)24

 = (42)24

 = 74

 



3)  

 Simplify   :   33 + 612 + 1124

Answer: 4724


SOLUTION 1 :

=     33 + 612 + 1124  

LCM of 3 12 .24 is  24

=  [(3x8) +(6x2) + (11x1)] / 24

= (24+12+11)24

 = (47)24

 = 4724

 



4)  

 Simplify   :   53 + 712 + 1024

Answer: 83


SOLUTION 1 :

=     53 + 712 + 1024  

LCM of 3 12 .24 is  24

=  [(5x8) +(7x2) + (10x1)] / 24

= (40+14+10)24

 = (64)24

 = 83
