-5/7-(-5/67)+13/30+1/2+(-1 5/6)+1 3/14-(-2/5)
bài 1: tính nhanh
a= ( 6-2/3+1/2)-(5+5/3-3/2)-( 3-7/3+5/2)
\(\dfrac{0,75+\dfrac{3}{5}-\dfrac{3}{7}-\dfrac{3}{13}}{2,75+2\dfrac{1}{5}-\dfrac{11}{7}-\dfrac{11}{3}}-\dfrac{0,75-\dfrac{3}{11}-\dfrac{1}{3}}{\dfrac{5}{22}-0,625+\dfrac{5}{18}}\)
a= ( 6-2/3+1/2)-(5+5/3-3/2)-( 3-7/3+5/2)
a,5(x-2)+3x (x-2)=0
b,2/3+5/2:x=2/4
c,2x(x-1/7)=0
d,11/12-(2/5+x)=2/3
e,3/4+1/4:x=2/5
g,2/3x+5/7=3/10
(3 - 1/4 + 2/3) - ( 5 + 1/3 - 6/5 0 - ( 6 - 7/4 + 3/2 )
Sắp xếp theo thứ tự tăng dần : -0,25 ; 1/2 ; -0,5 ; 5/6 ; 13/12 ; -5/24 ; 0 ; 1/48 ; 2/3 ; -9/8 .
