Option a: multiply by 4.
Explanation:
The expression is
Dividing the two fractions which is the same as multiplying the first fraction by the reciprocal value of the second fraction.
Hence, it can be written as
Hence, is the quotient.
Option a: multiply by 4.
To determine the quotient, let us multiply the term by 4, we get,
Hence, is the quotient.
Thus, Option a is the correct answer.
Option b: multiply by
To determine the quotient, let us multiply the term by 4, we get,
is not the quotient. Since, the quotient is
which is not equivalent to
and hence we cannot multiply
by
Hence, Option b is not the correct answer.
Option c: multiply by
To determine the quotient, let us multiply the term by
, we get,
is not the quotient. Since, the quotient is
which is not equivalent to
and hence we cannot multiply
by
Hence, Option c is not the correct answer.
Option d: multiply by 4
To determine the quotient, let us multiply the term by 4, we get,
10 is not the quotient. Since, the quotient 10 which is not equivalent to and hence we cannot multiply
by 4.
Hence, Option d is not the correct answer.
