làm giúp mình mình đang cần gấp
Tính nhanh nếu có thể.Câu1:(-1/2) -(-3/5) + (-1/9)+1/71-(-2/7)+4/35-7/18.Câu 2:(3-1/4+2/3)-(5-1/3-6/5)-(6-7/4+2/3)
(-1/2)- (-3/5)+ (-1/9)+ 1/71- (-2/7)+ 4/35- 7/18 ( tính nhanh nếu có thể)
Giup minh vs nha :)
tính nhanh nếu có thể
\(\left(-\frac{1}{2}\right)-\left(-\frac{3}{5}\right)+\left(-\frac{1}{9}\right)+\frac{1}{71}-\left(-\frac{2}{7}\right)+\frac{4}{35}-\frac{7}{18}\)
tính nhanh nếu có thể
\(\left(-\frac{1}{2}\right)-\left(-\frac{3}{5}\right)+\left(-\frac{1}{9}\right)+\frac{1}{71}-\left(-\frac{2}{7}\right)+\frac{4}{35}-\frac{7}{18}\)
-1/2+(-1/9)-(-3/5)+1/2006-(-2/7)-7/18+4/35
a) 11/125 - 17/18 - 5/7 + 4/7 + 17/14
b) (-1/2)-(-3/5)+(-1/9)+1/127-(7/18)+4/35-(-2/7)
Tinh hop li:
a.8/9-1/72-1/56-1/42-1/30-1/20-1/12-1/6-1/2
b.(-1/2)-(-3/5)+(-1/9)+1/127-(+7/18)+4/35-(-2/7)
c.3/5+3/11-(-3/7)+(2/97)-1/35-3/4+(-2/7)
