Answer 2

Answer:

3.27 bar on 27 is rational number​

Rational number:

p/q where q is not equal to 0 is the form of a rational number, which is a sort of real number in mathematics. A rational number is any fraction with a non-zero denominator. 1/2, 1/5, 3/4, and other like numbers are a few instances of rational numbers. The number "0" is also a rational number since there are various ways to express it, including 0/1, 0/2, 0/3, etc. However, since they provide us unlimited values, 1/0, 2/0, 3/0, etc. are illogical. Check the irrational numbers here as well and contrast them with the rational ones.

Step-by-step explanation:

$3.27 bar = 3.27272727... =$ say x.

$100 \times x = 327.27272727.....$

$100x - x = 327.2727....- 3.272727....$

$99 \times x = 324$

$x = 324 / 99$

Since x can be expressed in the form P/Q where P & Q are integers & Q is not zero, x is a rational number.

$3.27$ bar is a rational number.
