Tìm x:
\(\frac{\left(27\frac{5}{19}-26\frac{4}{13}\right)\left(\frac{3}{4}+\frac{15}{59}-\frac{3}{118}\right)}{\left(\frac{3}{4}+x\right)\frac{27}{33}}=\frac{\frac{1}{13.16}+\frac{1}{14.17}}{\frac{1}{13.15}+\frac{1}{14.16}+\frac{1}{15.17}}\)
Tính nhanh:
a) \(2\frac{13}{27}\)- \(\frac{7}{15}\)+ \(3\frac{14}{27}\)- \(\frac{8}{15}\)
b) \(11\frac{1}{4}\)- \(\left(2\frac{5}{7}+5\frac{1}{4}\right)\)
Thanks nhé , làm nhanh nhất mình sẽ tick đúng
Tinh nhanh
\(\frac{-27}{16}.\frac{4}{9}.\frac{5}{-7}.\frac{14}{15}\)
Tính:
\(\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6}+\frac{1}{7}-\frac{1}{8}+.....+\frac{1}{2015}-\frac{1}{2016}+\frac{1}{2017}.\)
\(\frac{5-\frac{5}{3}+\frac{5}{9}-\frac{5}{27}}{8-\frac{8}{3}+\frac{8}{9}-\frac{8}{27}}:\frac{15-\frac{15}{11}+\frac{15}{121}}{16-\frac{16}{11}+\frac{16}{121}}.\)
x2 =\(\frac{4}{5}.\frac{15}{27}\)
tìm x
\(\frac{x}{15}\)+\(\frac{27-x}{5}\)=\(\frac{x}{4}\)+\(\frac{27-x}{12}\)
giúp mình vs mn ....
Tìm x biết
a) \(\frac{x+5}{95}+\frac{x+10}{90}+\frac{x+15}{85}+\frac{x+20}{80}=-4\)
b) \(\frac{x-13}{87}+\frac{x-27}{73}+\frac{x-67}{33}+\frac{x-73}{27}=4\)
Giúp mình với !!!!!!!!!!!
Đúng;cách giải rõ ràng sẽ tick
