Question

so sánh 49/59 và 67/77 (s/sánh vs 1)

Answer 1

\(\dfrac{49}{59}=1-\dfrac{10}{59}\)

\(\dfrac{67}{77}=1-\dfrac{10}{77}\)

Vì 59<77

nên \(\dfrac{10}{59}>\dfrac{10}{77}\)

=>\(-\dfrac{10}{59}< -\dfrac{10}{77}\)

=>\(1-\dfrac{10}{59}< 1-\dfrac{10}{77}\)

=>\(\dfrac{49}{59}< \dfrac{67}{77}\)
