Write down the rational numbers in the form $\frac{p}{q}$ whose numerators and denominators are given below:(i) $(-5) \times 4$ and $-5+4$(ii) $64 ÷ 4$ and $32-18$

Given :

The numerators and the denominators are, 

(i) $(-5) \times 4$ and $-5+4$ 

(ii) $64 ÷ 4$ and $32-18$.

To do :

We have to rite the given numerators and the denominators in the form of $\frac{p}{q}$.

Solution :

(i) $(-5) \times 4$ and $-5+4$ 

Numerator (p) $= (-5) x 4 = -20$

Denominator (q) is $-5+4 = -(5-4) = -1$

Rational number $(\frac{p}{q}) = \frac{-20}{-1} = \frac{20}{1}$.

Therefore, $\frac{p}{q}$ form is $\frac{20}{1}$.

(ii) Numerator (p) $= 64 ÷ 4 = \frac{64}{4} = 16$

Denominator (q) is $32-18 = 14$

Rational number $(\frac{p}{q}) = \frac{16}{14} = \frac{8}{7}$.

Therefore, $\frac{p}{q}$ form is $\frac{8}{7}$.
