\(y=\dfrac{7}{8}:3=\dfrac{7}{8}\times\dfrac{1}{3}=\dfrac{7}{24}\)
\(\dfrac{7}{8}:y=3\)
\(y=\dfrac{7}{8}:3\)
\(y=\dfrac{7}{8}:\dfrac{3}{1}\)
\(y=\dfrac{7}{8}\times\dfrac{1}{3}\)
\(y=\dfrac{7}{24}\)
a,\(\dfrac{5}{7}\) x Y = \(\dfrac{3}{5}\)
b,\(\dfrac{1}{8}\) : y = \(\dfrac{3}{20}\)
tìm y ,biết : \(\dfrac{7}{2}\): y = \(\dfrac{3}{8}\) + \(\dfrac{5}{4}\)
y =
\(\dfrac{3}{7}\) + 4 = ?
\(\dfrac{5}{9}\) x 3 = ?
\(\dfrac{7}{8}\) - \(\dfrac{2}{9}\)= ?
5 - \(\dfrac{3}{4}\)= ?
\(\dfrac{5}{7}\) : 6 = ?
\(\dfrac{5}{6}\) x \(\dfrac{2}{7}\)= ?
3 + \(\dfrac{3}{4}\)= ?
\(\dfrac{3}{5}x\dfrac{4}{8}\) = ?
5 : \(\dfrac{3}{8}\)= ?
Mong mn trả lời
A,\(\dfrac{8}{9}:\dfrac{4}{5}+\dfrac{3}{5}\)
B,\(\dfrac{5}{8}\) + \(\dfrac{1}{4}\)
C,\(\dfrac{7}{8}\) x \(\dfrac{4}{7}\) +\(\dfrac{5}{9}\)
D,\(\dfrac{9}{8}:\dfrac{4}{3}-\dfrac{4}{7}\)
Tính :
a) 7 x \(\dfrac{3}{14}\) - \(\dfrac{1}{14}\) b) \(\dfrac{3}{2}\) + \(\dfrac{7}{4}\) x \(\dfrac{2}{5}\)
c) \(\dfrac{9}{8}\) : 3 + \(\dfrac{7}{8}\) : 3 d) 2 : \(\dfrac{3}{4}\) - \(\dfrac{5}{8}\) x \(\dfrac{4}{3}\)
Tính nhanh:
\(\dfrac{9}{8}x\dfrac{8}{7}x\dfrac{7}{3}x\dfrac{1}{3}\)
Phân số nào nhỏ nhất trong các phân số sau: \(\dfrac{6}{7}\);\(\dfrac{8}{7}\);\(\dfrac{12}{14}\);\(\dfrac{3}{4}\)
A. \(\dfrac{6}{7}\) B. \(\dfrac{8}{7}\) C. \(\dfrac{12}{14}\) D. \(\dfrac{3}{4}\)
Tìm 1 phân số \(\dfrac{x}{y}\) sao cho: \(\dfrac{7}{9}\)<\(\dfrac{x}{y}\)<\(\dfrac{7}{8}\) giải thích hộ mik luôn nha!
