TÍNH:
a) 1+1/4+1/8+1/16
b) 2-1/8-1/12-1/16
c) 4/99 x 18/5 : 12/11 +3/5
d) (1-3/4)x(1+1/3):(1-1/3)
1+1/4+1/8+1/6 ; 4/99x18/5:12/11+3/5 ; 2-1/8-1/12-1/16 ; (1-3/4)x(1+1/3):(1-1/3)
1/3+1/5......1/3 : 1/5
1/3-1/4.....1/3 * 1/4
11/12-11/12....2/3-1/4
Tìm x:
\(\dfrac{3}{5}\) : x = \(\dfrac{1}{3}+\dfrac{1}{2}\) x : \(\dfrac{7}{12}\) = 2 x - \(\dfrac{3}{2}\) = \(\dfrac{11}{4}-\dfrac{5}{4}\) x + \(\dfrac{5}{4}\) = \(\dfrac{3}{2}+\dfrac{7}{12}\)
tìm x
1) [(3/8.x-1/2):5/7+4/9].6/11=18/55
2) (7/10-3.x):( 1 9/10-1 2/5)+4/5=1
