What is the sum of 9 1/5, 4 3/10, and 6 5/6?

Sagot :

when adding or subtracting fractions, the very first thing to do is find the LCD.
the LCD for this case is 30. you will have:
       9 1/5          9 1(6)/30
+     4 3/10        4 3(3)/30
       6 5/6          6 5(5)/30
                      19  4/3
since 4/3 is an improper fraction that is equal to 1 1/3 then we'll have it expressed as 1 1/3. adding 19 to it you'll have the sum as:
    19 
+    1 1/3
    20 1/3
