Write an expression to represent: 3 minus the quotient of x and 4
alisha [4.7K]

The expression representing the sentence is $3 -\frac{x}{4}.

We have a sentence - "3 minus the quotient of x and 4".

We have to determine the expression that represents the sentence.

<h3>Express the statement - "The difference of x and y is equal to an irrational number" in the form of expression.</h3>

The expression representing the above statement is -

x - y = π.

According to the question, we have -

3 minus the quotient of x and 4.

Using the Division Algorithm -

x = 4q + r

Substituting r = 0 by introducing decimals in the quotient, we get -

q = $\frac{x}{4}

Therefore -

$3 -\frac{x}{4}

Hence, the expression representing the sentence is $3 -\frac{x}{4}.
