1.10119047619 use first 3 digits for answer

1  17/168

Step-by-step explanation:

3 1/3 is the same as 3 4/12

-2 1/4 is the same as -2 3/12

3 4/12 + (-2 3/12) = 1 1/12

1 1/12 + 1/56 = 13/12 + 1/56

we can use 168 as a common denominator to get:

13/12 = 182/168

1/56 = 3/168

add the above together to get 185/168 which is 1  17/168

good luck on your studies! : )
