Các bạn giúp mình bài này nha !
1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1
1/2 : 0,5 - 1/4 : 0,25 + 1/8 : 0,125 - 1/10 : 0,1
= 1 - 1 + 1 - 1
= 0 + 0
= 0
1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1
= 1 - 1 + 1 - 1
= 0 + 0
= 0
1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1 = 1
đồng ý vứi mình thì k nhé
Tinh gia tri bieu thuc : 170 + 9 + 6/100 + 3/10 ; tinh bang cach thuan tien : 1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1
Bài 1:
a) Tìm x: 75%* x+3/4*x +x=30
b)tính giá trị bieu thức: 1/2:0.5-1/4:0.25+1/8:0.125-1/10:0.1
Tính
A=1/2 /0.25-1/4/0.25+1/8/0.125-1/10/0.1
các bn giải rõ ràng cho mik nha
\(A=\frac{1}{2}:0,25-\frac{1}{4}:0,25+\frac{1}{8}:0,125-\frac{1}{10}:0,1\)
\(A=2-1+1+1\)
\(A=1+1+1\)
\(A=1.3\)
\(A=3\)
Vậy \(A=3\)
