Question

Calvin evaluated Negative two-thirds times 5 and one-sixth using the steps below. Step 1: Negative two-thirds time (5 + one-sixth) Step 2: (Negative two-thirds + 5) times (Negative two-thirds + one-sixth) Step 3: 4 and one-third times negative one-half Step 4: Negative 2 and one-sixth Which describes Calvin’s error?

Answer 1

Answer:

Step-by-step explanation:

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

(-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)
