Which two whole numbers does the fraction below lie between 31/5
Eddi Din [679]

Answer: 6 and 7

Step-by-step explanation:

For this exercise it is important to remember that Whole numbers Set contains the positive numbers and zero with no fractional part and with no decimal part.

Rational numbers are those numbers that can be written as a fraction, in this form:

\frac{a}{b}

Where "a" is the numerator and "b" is the denominator. Both are integers.

Then, given the following fraction:

\frac{31}{5}

You can express it as a decimal number by dividing the numerator 31 by the denominator 5:

\frac{31}{5}=6.2

Based on the definition of Whole numbers, you can identify that:

6

So the given fraction lies between the following Whole numbers:

6 and 7
