Giải nhanh giùm mình nha các bạn
Tính
a) \(\left(-\frac{2}{3}+\frac{3}{7}\right):\frac{4}{5}+\left(-\frac{1}{3}+\frac{4}{7}\right):\frac{4}{5}\)
b) \(\frac{5}{9}:\left(\frac{1}{11}-\frac{5}{22}\right)+\frac{5}{9}:\left(\frac{1}{15}-\frac{2}{3}\right)\)
Tìm x, biết:
a) ( x - 15 ) : 5 + 22 = 24
b) | x + 7 | = 15 - ( -4 )
c) \(\left(x-\frac{1}{2}\right)\div\frac{1}{3}+\frac{5}{7}=9\frac{5}{7}\)
