FIRST STEP: parenthesis

Answer 2

13 - 101/3 + 22/3 = ?

I would first clear the fractions by multiplying both sides by 3/3, which is the same as 1, so you are not changing anything.

13x3/3 - 3x101 /3x3 + 22x3/3x3

39/3 - 303/9 + 66/9

you can combing the right two fractions

39/3 - 237/9

you can multiply 39/3 by 3/3 to make them have the same denominator

3/3*39/3 - 237/9

117/9 - 237/9 = -120/9

Simply top and bottom by dividing by 3

-40/3
