Question

The standard form of a rational number 45/(-60) is

Answer 1

Answer:

3/(-4) ...this is the right answer because both are forgivable by 15 so

divide 15 by them and find the answer

Answer 2

The standard form of a rational number $\frac{45}{-60}$  is  $\frac{3}{-4}$ .

• A rational number is a number of the form p / q where p and q are integers and q ≠ 0.

• The standard form of a rational number is its simplest reduced form, such that the numerator p and the denominator q do not have any factor in common other than 1.

• In the given rational number $\frac{45}{-60}$ , both 45 and 60 are divisible by 15.

This means, 15 is the factor common to both.

• Now, dividing 45 by 15, we get 3, and

dividing - 60 by 15, we get - 4.

• Therefore, the simplest form of the number is $\frac{3}{-4}$ and it cannot be reduced further. Hence, the standard form of  $\frac{45}{-60}$  is  $\frac{3}{-4}$ .
