1/2+1/16 = x
Step 1
Look for common factors of their denominators
2- 2,4,6,8,10,12,14,16
16-16,32,48

16 is the least common multiple
Change the denoniminators by 16 you must divide the LCM by the current denominator of 1/2 which is 2
2÷16= 8
multiply the quotient to the numerator.
1×8= 16
Change it
8/16.
do the same to the other fraction
*16÷16=1
*1×1=1
*1/16

There you have it
now solve it
8/16+1/16=9/16

Thats how you get the LCD
