What is 1 1/2 + 1 2/3

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
