bye bye
Chia thành số tự nhiên : 4 : 3 = 1 (dư 1 )
Chia thành phân số : \(4:3=\frac{4}{3}\)
C 1 : 4 chia 3 là tứ chia tam là 8 chia 4 = 2
C2 :4 chia 3 = 4/3
7x7=?
8x8=?
9x9=?
ket bn voi mk nhe!
7 x 7 = 49
8 x 8 = 64
9 x 9 = 81 nha bạn nhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Thực hiện phép tính sau:
3/7x7/3x7/3x3/7x7/3
\(=\dfrac{3}{7}\cdot\dfrac{7}{3}\cdot\dfrac{7}{3}\cdot\dfrac{3}{7}\cdot\dfrac{7}{3}=1\cdot1\cdot\dfrac{7}{3}=\dfrac{7}{3}\)
7x7=?
GIÚP MK NHA MK TICK CHO !
7 x 7 = 49 bn nha
~ chúc các bn thi tốt . Ai thấy đúng thì tk mk nha ~
3/2-1/5=
3/7x7/6=
1/5:3/10=
3/2-1/5= 15/10 - 2/10 = 13/10
3/7x7/6= 21/42 = 1/2
1/5:3/10= 1/5 x 10/3 = 10/15 = 2/3
