Question

Express 1.25 as rational number

Answer 1

125/100 is the rational number for that

Answer 2

Answer:

The rational form of 1.25 = $\frac{5}{4}$

Step-by-step explanation:

Recall the concept

A rational number is a number of the form $\frac{p}{q}$ , where p and q are integers and q ≠ 0

We can express every terminating decimal as a rational number

In order to express 1.25 as a rational number, we should multiply and divide the number by 100 (we are using 100 as there are 2 decimal places)

1.25 = $\frac{1.25 X 100}{100}$ = $\frac{125}{100}$

Now simplify the numerator and denominator to get the fraction in the simplest form

$\frac{125}{100} = \frac{5}{4}$

∴ The rational form of 1.25 = $\frac{5}{4}$
