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:
D.There is no error.
Step-by-step explanation:
We are given that Jacob is showing his steps to solve the expression
We have to find the error in Jacob steps in which he makes error
Jacob writes his first step
Step:1
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
Hence, Jacob's second step is right.
Now , we multiply -27.8 with 7 then we get
Step:3
Hence, Jacob's third step is also right.
Therefore, Jacob makes no error in his steps.
Hence, Option D is true.
1. A rational number is a number that can be written as a fraction.
For example: 1/3, 5/7, 90/666, etc
Note: Any integer can be written as a fraction.
Look:
5 = 5/1 = rational
-14 = -14/1 = rational
2. There is no difference between a rational and integer.
