2*x+1/2*x + 6*x+1/6*x +12*x+1/12*x +20*x+1/20*x= 5.tìm x
tìm x
x-6 1/2=6 1/3+6 1/6
x-3/7=1/2+3/7
x-3/5=1/3:1/6
x:3/2=5/6-3/8
2*x+1/2*x+6*x+1/6*x+12*x+1/12*x+20*x+1/20*x=5.Tim x
Tính:
a) (6 : dfrac{3}{5} 1dfrac{1}{6} x dfrac{6}{7} ) : ( 4dfrac{1}{5} x dfrac{10}{11} + 5dfrac{2}{11} )
b) (1-dfrac{1}{2}) x (1-dfrac{1}{3}) x (1-dfrac{1}{4}) x ..... x (1-dfrac{1}{2003}) x (1-dfrac{1}{2007})
Đọc tiếp
Tính:
a) (6 : \(\dfrac{3}{5}\) \(1\dfrac{1}{6}\) x \(\dfrac{6}{7}\) ) : ( \(4\dfrac{1}{5}\) x \(\dfrac{10}{11}\) + \(5\dfrac{2}{11}\) )
b) (\(1-\dfrac{1}{2}\)) x (\(1-\dfrac{1}{3}\)) x (\(1-\dfrac{1}{4}\)) x ..... x (\(1-\dfrac{1}{2003}\)) x (\(1-\dfrac{1}{2007}\))
3/5 + 2/5 : x = 1 1/10
( x - 3/5) x 3/8 - 5/8 = 1/6
1 1/6 - 5/6 : ( x+1/4) = 1/2
