Given :
- Henry takes a math test that had 20 questions.
- He answered 17 questions correctly and 3 questions incorrectly.
The following steps can be used in order to determine the percentage of correct and incorrect questions Henry answered:
Step 1 - The unitary method can be used in order to determine the percentage of correct and incorrect questions Henry answered.
Step 2 - The total number of questions in a math test is 20. The total number of correct answers is 17 and the total number of incorrect answers is 3.
Step 3 - If the 20 is the 100% questions then the percentage of 17 correct answers is:

= 85%
Step 4 - If the 20 is the 100% questions then the percentage of 3 incorrect answers is:

Answer:
The Product is negative three (-3)
WHILE
The number is negative one (-1)
Step-by-step explanation:
Since seven more than the product gives 4.
This means 7 + product = 4
By subtracting 7 from both sides we get product as -3.
And since the product of the number and 3 is equal the product
This means number X 3 = -3
By dividing three from both sides you get -1.
