3 1/6
To do this, you must change 1 1/2 to 1 3/6 by multiplying the fraction by 3/3
and 1 2/3 to 1 4/6 by multiplying the fraction by 2/2
then, you just add normally: 1 3/6 + 1 4/6
= 3 7/6 = 4 /16
the answer is 4 1/6 or in irregular form, 25/6
1 1/2 + 1 2/3
= 2 + 1/2 + 2/3
= 2 + 3/6 + 4/6
= 2 + 7/6
= 3 1/6 answer
