𝑥=\(\dfrac{109}{432}\)
Chúc em học tốt !
Cho xin một like đi các dân chơi à.
\(x-\dfrac{1}{4}=\dfrac{5}{9}:\dfrac{15}{16}\)
\(x-\dfrac{1}{4}=\dfrac{16}{27}\)
\(x=\dfrac{16}{27}+\dfrac{1}{4}\)
\(x=\dfrac{91}{108}\)
\(x-\dfrac{1}{4}=\dfrac{5}{9}:\dfrac{15}{16}\\ \Rightarrow x-\dfrac{1}{4}=\dfrac{5}{9}.\dfrac{16}{15}\\ \Rightarrow x-\dfrac{1}{4}=\dfrac{16}{27}\\ \Rightarrow x=\dfrac{16}{27}+\dfrac{1}{4}\\ \Rightarrow x=\dfrac{91}{108}\)
