= 4/7
= 10/6 = 1 4/6
= 30/1 = 30
= 20/5 = 4
nha
2/7+2/7=4/7
6/6+4/6=10/6=5/3
23/1+7/1=30/1=30
10/5+10/5=20/5=4
dung tk mik nha thank you . Chuc ban hoc gioi nhe
2/7+ 2/7= 4/7
6/6+ 4/6=10/6
23/1+ 7/1= 30/1
10/5+ 10/5= 20/5
1)=4/7
2)=10/6=5/3
3)=30
4)=4
ai tích mình mình tích lại
các bạn nhớ nhé
2 / 7 +2/7 =4/7
6/6 + 4/6 = 5/3
23/1 + 7/1 = 30
10/5 +10/5 = 4
Cách 1:
\(\frac{2}{7}+\frac{2}{7}=\frac{2+2}{7}=\frac{4}{7}\)
Cách 2:
\(\frac{2}{7}+\frac{2}{7}=\frac{2}{7}\cdot2=\frac{2}{7}\cdot\frac{2}{1}=\frac{4}{7}\)
\(\frac{6}{6}+\frac{4}{6}=\frac{6+4}{6}=\frac{10}{6}=\frac{10:2}{6:2}=\frac{5}{3}\)\(=1\frac{2}{3}\)
\(\frac{23}{1}+\frac{7}{1}=23+7=30\)
\(\frac{10}{5}+\frac{10}{5}=\frac{10+10}{5}=\frac{20}{5}=4\)Cách 1
\(\frac{10}{5}+\frac{10}{5}=\frac{10}{5}\cdot2=\frac{10}{5}\cdot\frac{2}{1}=\frac{20}{5}\)\(=4\)Cách 2
K mk nhé thanks bạn nhìu nhìu mk nhanh nhất nha
ai k mk 1 cái mk k cho 3 cái nha thanks
