Answer 1

It is rational. as it can be written in the form of p/q where q≠0.

Answer 2

Concept

In arithmetic, a rational number is one that can be expressed as the quotient p/q of two numbers with q ≠ 0 . The set of rational numbers also includes all the integers, which can be expressed as a quotient with the integer as the numerator and 1 as the denominator.

Given

$1.23+3/4$

Find

We are asked to state whether

$1.23 + 3 /4$

is a rational number

Solution

By considering given figures

$1.23+3/4\\\frac{123}{100} +\frac{3}{4} \\\frac{123+75}{100} \\\frac{198}{100}$

Which is in the form of p/q where q ≠ 0 therefore

$1.23 + 3 /4$

is a rational number.

Hence 1.23+3/4 is a rational number.
