Mong mn trả lời
\(\dfrac{2}{5}\) x \(\dfrac{3}{4}-\dfrac{1}{8}\) \(= \)
\(\dfrac{4}{3}+\dfrac{1}{3}-\dfrac{1}{5}=\)
\(\dfrac{9}{20}-\dfrac{3}{5}\) x \(\dfrac{1}{4}\)\(= \)
\(\dfrac{2}{8}+\dfrac{2}{3}:\dfrac{4}{5}\)\(=\)
a,\(\dfrac{4}{9}\) : \(\dfrac{3}{10}\)
b,\(\dfrac{3}{7}\) x \(\dfrac{5}{7}\)
c,\(\dfrac{4}{9}\) : \(\dfrac{3}{2}\)
D \(\dfrac{3}{9}\) + \(\dfrac{5}{6}\) x \(\dfrac{2}{3}\)
E \(\dfrac{2}{7}\) x \(\dfrac{4}{3}\) + \(\dfrac{2}{6}\)
G \(\dfrac{4}{7}\) : 2 + \(\dfrac{4}{7}\)
a.\(\dfrac{2}{7}\) x \(\dfrac{4}{3}\) + \(\dfrac{2}{6}\)
B.\(\dfrac{4}{7}\) : 2 + \(\dfrac{4}{7}\)
C.\(\dfrac{1}{3}+\dfrac{3}{4}-\dfrac{1}{5}:\dfrac{2}{3}\)
\(\dfrac{3}{4}+\dfrac{5}{8}=?\) 6 - \(\dfrac{3}{7}=?\)
\(\dfrac{3}{4}X\dfrac{2}{5}=?\) \(\dfrac{3}{7}:\dfrac{4}{9}=?\)
Tính :
\(\dfrac{1}{2}\) + \(\dfrac{1}{3}\) - \(\dfrac{1}{5}\)
\(\dfrac{1}{5}\) : \(4\) + \(\dfrac{3}{4}\)
\(\dfrac{4}{3}\) x \(\dfrac{9}{5}\) - \(\dfrac{3}{10}\)
Tính
a.\(\dfrac{4}{9}+\dfrac{3}{7}\) \(\dfrac{3}{4}+\dfrac{7}{24}\) \(\dfrac{1}{3}+\dfrac{2}{9}+\dfrac{4}{27}\)
b.\(\dfrac{5}{6}-\dfrac{3}{8}\) \(\dfrac{7}{15}-\dfrac{11}{30}\) \(\dfrac{2}{3}+\dfrac{1}{6}-\dfrac{7}{12}\)
c.\(\dfrac{18}{25}\times\dfrac{15}{6}\) \(\dfrac{30}{49}:\dfrac{6}{7}\) \(\dfrac{1}{2}\times\dfrac{3}{4}:\dfrac{6}{5}\)
d.\(8\times\dfrac{3}{5}:\dfrac{12}{5}\) \(4:\dfrac{9}{5}:\dfrac{10}{3}\)
3 bn đầu tiên xong mik sẽ tick
Bài 1 : TÍNH
\(\dfrac{2}{3}+\dfrac{3}{10}\) ; \(\dfrac{2}{3}-\dfrac{5}{8}\) ; \(\dfrac{3}{7}\) x \(\dfrac{4}{9}\) ; \(\dfrac{5}{6}:\dfrac{4}{3}\)
BÀI 2 : TÌM \(x\)
a) \(\dfrac{5}{4}-x\) bằng \(\dfrac{2}{3}\) b) \(x:\dfrac{3}{5}b\text{ằng}4\)
giải giúp mik với. đi mà. làm ơn. GIẢI RÕ RÀNG VÀ Đ CHO MIK VỚI NHA. CẢM ƠN AH
\(x\) x \(\dfrac{1}{5}\) = 1 - \(\dfrac{2}{3}\)
\(x\) : \(\dfrac{3}{4}\) = ( \(\dfrac{2}{3}\) + \(\dfrac{1}{3}\) ) : \(\dfrac{3}{4}\)
