3 divided by 4 can be written as 3/4. How are the dividend and divisor of a division expression related to the parts of a fraction?

I'm not sure what you exactly mean, but you generally divide the dividend by the divisor of a division expression and you get the result. Sometimes it's impossible to get a readable result (like i. e. 2/3), so we write it as a fraction making it the result itself.

For this case we have the following division:

3 divided by 4

The dividend in this case is number 3.

The divisor in this case is number 4.

Rewriting the division as a fraction we have:

3/4

We observed that:

The dividend is the numerator of the fraction.

The divisor is the denominator of the fraction.

Answer:

The dividend and divisor of a division expression are related to the parts of a fraction in the following way:

The dividend in this case is number 3.

The divisor in this case is number 4.
