Answer 2

Answer:

(a) $\frac{-21}{63}$ = $\frac{-3}{9}$ (Divide numerator and denominator by 7)

(b)$\frac{2}{-5}$ = $\frac{-2}{5}$

(c) $\frac{-15}{-105}$ = $\frac{1}{7}$ (Negative upon negative is positive. Ex: -21 ÷ -7 = 3. Also divide numerator and denominator by 15)

(d)$\frac{16}{-112}$ = $\frac{-1}{7}$ (Divide numerator and denominator by -16)

(e) $\frac{-9}{3}$ = $\frac{-3}{1}$ (Divide numerator and denominator by 3)

(f) $\frac{8}{-40}$ = $\frac{-1}{5}$ (Divide numerator and denominator by -8)
