`6/8` - `x` = `3/9`
=> `x` = `6/8` - `3/9`
=> `x` = `5/12`
Tính: a) 3 x 4 x 7 / 5 x 3 x 4 b) 2 x 5 x 6 x 8 / 6 x 2 x 8 x 9 c) 4 x 5 x 6 / 3 x 10 x 8
5/6 + 5/8 + 3/4
12/15 + 3 + 3/5
4/3 x 7/8 x 5
8/9 x 6/5 : 3
7/12 + 5/8 x 4/3 - 3/4
(8/5 - 7/6) : 13/15 + 1/4
Bài 3: Tính bằng hai cách
a 1/8 x 5/6 + 5/6 x 2/3
b 7/5 x 3/4 - 1/2 x 3/4
c (5/6 + 5/8) x 2/3
Bài 3: Tính bằng hai cách
a 1/8 x 5/6 + 5/6 x 2/3
b 7/5 x 3/4 - 1/2 x 3/4
c (5/6 + 5/8) x 2/3
Tính :
a) 4 x 6 x 8 / 6 x 12 x 16
b) 3 x 4 x 5 x 6 / 9 x 8 x 10 x 3
Tính :
a) 4 x 6 x 8 / 6 x 12 x 16
b) 3 x 4 x 5 x 6 / 9 x 8 x 10 x 3
1) 1/3 x 1/2 x 3/7 2) 5/4 x 1/3 + 1/7 3) 8 x ( 8/9-2/3 ) 4) 5/6 x 48/20 x 1/2 5) ( 2/5 + 3/4 ) x 8 6) 10 x ( 1/2-1/5 )
Tính bằng hai cách
a, 1/8 x 5/6 + 5/6 x 2/3
b, 7/5 x 3/4 - 1/2 x 3/4
c, (5/6 + 5/8) x 2/3
mấy bạn cố lên nha
tính
b) 2 - 8/9 =
c) 5/8 x 3 =
d) 5 : 6/21=
đ) 3/5 x 4/5 x 6/7=
