3 3/6 is equal to 21/6 1 2/3 is equal to 5/3 Both 3 and 6 go into 6 so the denominator is 6 Now multiply 5 by 2 because 3 goes into 6 twice. 10/6 You don't need to change 21/6 because the denominator is already 6 So now you need to add them 21/6+ 10/6= 31/6 Which is also 5 1/6 So the overall answer is 5 1/6
