Question

Jacob is showing his steps to solve the expression −27.8 ÷ 1 over 7.

In which step did Jacob make an error?

Step 1: −27.8 ÷ 1 over 7
Step 2: −27.8 ⋅ 7

Step 3: −194.6

Step 1

Step 2

Step 3

There is no error.

Answer 1

There is no error, Jacob did everything right :)

Answer 2

D.There is no error.

Explanation:

We are given that Jacob is showing his steps to solve the expression

`-27.8/(1)/(7)`

We have to find the error in Jacob steps in which he makes error

Jacob writes his first step

Step:1
`-27.8/ (1)/(7)`

Jacob's first step is true.

We know that if we changes divide sign of term into multiply then the the term which is write on right side of divide sign reciprocal. Therefore,

Step:2
`-27.8*7=-27.8\cdot 7`

Hence, Jacob's second step is right.

Now , we multiply -27.8 with 7 then we get

Step:3
`-27.8\cdot7=-194.6`

Hence, Jacob's third step is also right.

Therefore, Jacob makes no error in his steps.

Hence, Option D is true.
