4/5+4/5+4/5+4/5.....4/5*5 4/5*4..........4/5*5
điền dấu đó nha
làm ơn giúp mình nhanh gấp
a.2/3 × 5/4 + 2/3 × 4/5 = ........ × ( 5/4 + 4/5 )
b. 5/2 × (3/7 + 1/5 ) = ...
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
Điền dấu cộng trừ nhân chia để có kết quả là:1
a)4 4 4 4 4
b)5 5 5 5 5
