Simplifique esta solución Beyond the Answer
The calculation \( 5 \times 1.5 = 7.5 \), so this number is real. Since 7.5 can be expressed as \( \frac{75}{10} \), it is also a rational number. Thus, you have a real, rational number! If you're looking to explore more about rational numbers, did you know that a rational number can always be expressed as a fraction of two integers? Meanwhile, an irrational number, like the square root of 2, can't be expressed in such a manner, which adds a layer of mystery to their properties!
