​

Answer 1

Answer:

If is written as rational number with denominator 30, then its numerator

would be 18

Answer 2

Complete question:

If 3:-5 is written as a rational number with denominator 30, then its numerator would be​:

a) 6

b) 18

c) -6

d)-18

Answer:

The numerator of the resultant rational number becomes -18.

Step-by-step explanation:

Given,

The fraction 3/(-5)

To find,

The numerator of the rational number, when the fraction 3/(-5) is written in the form of a rational number with denominator 30.

Calculation,

As the given fraction is 3/(-5) and said the denominator is 30

So, we try to multiply and divide the fraction by (-6) so that the denominator will be 30

i.e. The denominator of the fraction 3/(-5), when multiplied by (-6), is:

(-5) × (-6) = 30

Now we should also multiply the same to the numerator of the fraction 3/(-5).

Hence, (3) × (-6) = -18

Therefore, the numerator of the resultant rational number becomes -18.
