Question

Express 2/-3 as a rational number with denominator: -15 ,18

Answer 1

hey!!

here is your answer >>>

2/-3

With denominator -15!.

We have to multiply -3 with 5, then, we will have to multiply the neumerator also with 5..

It will become :-

10/-15

With denominator 18, we have to multiply both the neumerator and denominator with -6. we get.

-12/18! ..

Hope my answer helps! ✌️

Answer 2

Hello mate,
Here is your answer,

★ To show -⅔ with denominator -15 :

We must multiple the LCM of 3 and 15 with -⅔ (in both numerator and denominator),

LCM of 3 and 15 is 5.
Hence,

$- \frac{2}{3} \times \frac{5}{5} \\ = - \frac{2 \times 5}{3 \times 5} \\ = - \frac{10}{15} \\ = \frac{10}{ - 15}$

★ To show -⅔ with denominator 18:

As we have done in the above part,
we have to multiple the LCM of 3 and 18 with -⅔ (in numerator and denominator),

LCM of 3 and 18 is 6
Hence,

$- \frac{2}{3} \times \frac{6}{6} \\ = - \frac{2 \times 6}{3 \times 6} \\ = - \frac{12}{18} \\ = \frac{ - 12}{18}$



Hope this helps

Thank you
