Bài 7: Tính
a, 2/5 + 3/4 = ...........................................................................
b, 2/5 + 3/10 - 1/2 = .................................................................
c, 8/11 + 8/33 x 3/4 = ...............................................................
8/11 + 8/33 x 3/4
Tính:
\(\dfrac{8}{11}-\dfrac{8}{33}\) χ \(\dfrac{3}{4}\)
1. 8/11 + 8/33 x 3/4
7/9 x 3/14 : 5/8
5/12 - 7/32 : 21/16
Bài 1 : Tính
a) 3/7 + 9/8 = ?
b) 4/5 - 2/15 = ?
c) 8/11 x 33/5 = ?
d) 4: 1/7 = ?
8/11 +8/33 nhân 3/4
Tính nhanh
M = \(\dfrac{3}{5}\) x (\(\dfrac{6}{7}\) x \(\dfrac{8}{9}\) x \(\dfrac{10}{11}\)x ...\(\dfrac{32}{33}\) )
8/11 + 8/33 x 3/4
giúp mình với
Tím X
X x 11/8 = 33/20
5: x = 4/7
Điền dấu : >,<,=
a,5/3 x 7/10 .... 5/7 : 7/10
b, 4/5 x 5/6 ..... 8/9 : 4/3
c, 5/11 x 33/15 ..... 6/17 x 34/25
d, 15/19 x 38/5 ..... 15/16 : 3/8
Mong mn làm giúp ạ
