Step-by-step explanation:

-2/3 * 5 1/6 step 1correct

(-2/3 * 5) + (-2/3 * 1/6)his error is here...it should be like I have written it, but Calvin is getting his addition and multiplication mixed up

-10/3 + (-1/9) =

-30/9 - 1/9 =

-31/9 =

- 3 4/9

so he messed up in step 2

he is doing this : (-2/3 + 5) * (-2/3 + 1/6)...when he should be doing this :

(-2/3 * 5) + (-2/3 * 1/6)
