so sánh 52/17 và 120/41
3/4 + 1/4 : ( 7/12 - 1/6 )
372,463 x 998 + 744,926
2- 4 + 6 - 8+ 10 - 12 +........ + 98 - 100 + 102
( y + 112) - 113=79
3/4 - y = 1/2
(4/5 - 2 x y) + 1/6= 5/6
(Y + 1) + ( Y + 2 ) + ( Y + 3)+........+ (Y + 50 ) = 1750
Gỉai giúp t bài này với ạ mơn các c rất nhiều ạ giải chi tiết giùm t với ạ t mơn nhìu ạ
Tính giá trị biểu thức sau : 6 \(\frac{3}{5}:6-\frac{1}{8}\times8+\frac{1}{3}\times\frac{3}{50}\)
a)1/3+2/3.?(2.x-1/2)=2
b)0,5.x+2/3.x+2/3=7/12
c)3/5-2/15:x=1/2
d)50%.x-2và1/2=2và5/6
e)(2và4/5.x-50):2/3=51
f)(4và1/2-2.x).3và2/3=11/15
g)2/5-( 2và1/2.x-3):15=1/10
h)(3/4=x).1/2=5và1/6-1và1/6
làm ơn giải giúp mik với. nhớ ghi cách giải ra hộ mik nha.mik tick cho

1+2+3+4+5+6+7...+50=?
1.Tìm x
a. ( 2 4/5 * x - 50 ): 2/3 =51
b.2/5 - ( 2 1/2 * x - 3 ) : 15 = 1/10
c.( 3/4 + x ) * 1/2 = 5 1/6 - 1 1/6
