Need answer now please answer and don't give any rubbish answer otherwise I'll report the answer​

Answer 1

Answer:

(a) 25/(-45) (b)-35/63

Step-by-step explanation:

$\frac{ - 5}{9} = \frac{ - 5 \times 5}{9 \times 5} = \frac{ - 25}{45} = \frac{25}{ - 45}$

$\frac{ - 5}{9} = \frac{ - 5 \times 7}{9 \times 7} = \frac{ - 35}{63}$

Answer 2

Answer:

$-\frac{25}{45} ,\frac{35}{63}$

Step-by-step explanation:

• As per the data given in the question, we need to express the rational number $-\frac{5}{9}$ as a rational number with denominators $-45$ and $63$

(a)

• To express $-\frac{5}{9}$ as a rational number with denominator $-45$, we need to multiply the numerator and denominator by $5$

• On multiplying the numerator and denominator of the fraction $-\frac{5}{9}$ by $5$, we get

$-\frac{5\times5}{9\times5}$

$=-\frac{25}{45}$

• To express $-\frac{5}{9}$ as a rational number with denominator $63$, we need to multiply the numerator and denominator by $-7$

• On multiplying the numerator and denominator of the fraction $-\frac{5}{9}$ by $7$, we get

$-\frac{5}{9}\times-\frac{7}{7}$

$=\frac{35}{63}$

Hence, the rational numbers are $-\frac{25}{45} ,\frac{35}{63}$.
