\(x=\dfrac{4}{7}:\dfrac{5}{9}\)
\(x=\dfrac{4}{7}\times\dfrac{9}{5}\)
\(x=\dfrac{36}{35}\)
\(x=\dfrac{4}{7}:\dfrac{5}{9}\)
\(x=\dfrac{4}{7}\times\dfrac{9}{5}\)
\(x=\dfrac{36}{35}\)
Tính giá trị biểu thức :
\(\dfrac{9}{5}-\dfrac{3}{4}:\dfrac{5}{6}=?\)
Tìm x :
\(\dfrac{7}{9}:x=\dfrac{5}{7}\)
a) Tính giá trị biểu thức :
\(\dfrac{7}{5}x\dfrac{3}{4};\dfrac{4}{5}\)
b) Tìm x :
\(x-\dfrac{3}{9}=\dfrac{8}{7}\)
giải hộ mik nha , giải rõ ràng , chi tiết cho mik ra nhá
Bài 1 : Tính
a) \(\dfrac{7}{12}+\dfrac{3}{4}\) x \(\dfrac{2}{9}\) b) \(\dfrac{8}{9}-\dfrac{4}{15}\) : \(\dfrac{2}{5}\)
tìm x:
a) \(\dfrac{24}{35}\) - x = \(\dfrac{2}{7}\)
b) x - \(\dfrac{5}{6}\) = \(\dfrac{7}{8}\)
c) x - \(\dfrac{11}{5}\) = \(\dfrac{2}{5}\) : \(\dfrac{2}{3}\)
(giải chi tiết hộ mình)
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
