Điền dấu < , > , =
a) 4/5 + 4/5 + 4/5 + 4/5 ..........4/5 x 5
b) 4/5 x 4 .........4/5 x 5
Mình sẽ tích cho ai có câu trả lời nhanh và đầy đủ .
a.2/3 × 5/4 + 2/3 × 4/5 = ........ × ( 5/4 + 4/5 )
b. 5/2 × (3/7 + 1/5 ) = ...

điền dấu đó nha
làm ơn giúp mình nhanh gấp
Tìm x biết :
x + 4/5 = 4/5 + ( 3/7 + 3/5 ) 5/7 + x/35 = 4/5
x < 3/4 + 2 2/3 + 1 < x < 5/6 + 4
x< 5/6 - 3/4 2/3 < x < 2 - 5/6
tìm x
x+4/5=4/5+(3/7+3/5
5/7+x/35=4/5
Tính :
a ) 2/5 + 4/5 : 5/6 =
b ) 7/3 - 2/3 x 4/5 =
c ) 6/5 : 10 x 5/2 =
d ) 4 : 8/9 + 3/4 =
3/5 + 11/20 =
4/7 : 8/11 =
5/8 - 4/9 =
3/5 + 4/5 : 2/5 =
