in the form of Equivalent Fraction can be written as
, where "x" is any integer.
As per the question statement, we are provided with a fraction, .
We are required to rewrite the above mentioned fraction in the form of a general Equivalent Fraction.
To solve this question, we need to know what an equivalent fraction is.
Equivalent fractions are those fractions that have different numerators and denominators but are equal to the same value, when simplified.
For example, all equate to
when simplified.
Now, for this case, equivalent fractions of are
, where
i.e., the equivalent fractions of are in the form of
, where "x" can be any integer, (...-6, -5, -4, -3, -2, -1, 2, 3, 4, 5, 6...)

Answer: 5
Step-by-step explanation:
Let A denotes the number of major defects and B denotes the number of design defect.
By considering the given information, we have
Now, the number of major defects or design defects:
Also,
Hence, the number of design defects were major=5
