Question

What is the LCD (least common denominator) of:

9/26 + 3/13

Answer 1

the least common denominator is 26

Answer 2

The least common denominator of 26 and 13 is 26. Both 26 and 13 are divisible by 13, therefore, it must be 26, and 13 cannot be divided by 26 to get a whole number. The fractions then become 9/26 + 6/26= 15/26 Hope this helps :)
