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
rút gọn rồi tính:
33/15 x 35/21 x 63/14 x 9/30
Tìm X
A) X : 9/22 = 44
B) X : 5/11 = 33
C) X : 4/33 = 22
rút gọn rồi tính :
a . 33/ 22 x 15/35
b. 16 / 9/4
c. 88 / 72 x 3/4
11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30+31+32+33+34+35+36+37+38+39+40
4/15 +1/2
51/9 - 2/3
3/4 x 15/26
7/3 : 5/14
4/15 1/2
51/9 - 2/3
3/4 x 15/26
7/3 : 5/14
9 x 11 x 36 / 33 x 27 x 18
Rút gọn phân số : a) 42 / 15 x 7 b) 35 x 6 / 336 c) 4 x 33 / 11 x 12 d) 9 x 4 + 9 x 11 + 5 x 9 / 63
