Question

ajuda agorrrrra urgente

Answer 1

a) $\dfrac{a}{b}=\dfrac{14}{10}=\dfrac{14\div2}{10\div2}=\dfrac{7}{5}$

b) $\dfrac{a}{b}=\dfrac{-20}{-16}=\dfrac{-20\div(-4)}{-16\div(-4)}=\dfrac{5}{4}$

c) $\dfrac{a}{b}=\dfrac{-49}{42}=\dfrac{-49\div7}{42\div7}=\dfrac{-7}{6}$

d) $\dfrac{a}{b}=\dfrac{22}{-121}=\dfrac{22\div(-11)}{-121\div(-11)}=\dfrac{-2}{11}$

Answer 2

a)

a=14 e b=10 => 14/10=7/5 (divisão por 2)

b)

a=20 e b=-16 => 20/-16=-5/4 (divisão por 4)

c)

a=49 e b=42 => 49/42=7/6 (divisão por 7)

d)

a=22 e b=-121 => -2/11 (divisão por 11)
