Bài 1 : Tính
a)\(5+\frac{3}{5}\)
b)\(10-\frac{9}{16}\)
c)\(\frac{2}{3}-\left(\frac{1}{6}+\frac{1}{8}\right)\)
d)\(\frac{15}{16}:\frac{25}{24}\)
e)\(14x\frac{5}{21}\)
g)\(\frac{5}{3}:10\)
h)\(10:\frac{5}{3}\)
Bài 2 :
a)\(\frac{9}{22}x\frac{33}{18}\)
b)\(\frac{12}{35}:\frac{36}{25}\)
c)\(\frac{19}{17}:\frac{76}{51}\)
bn ra từng câu 1 thui đừng ra nhìu làm chán lém
10-9/16=91/10
5+3/5=28/5
3/8
9/10
10/3
1/6
50/3
B2
3/4
5/21
51/28
Bài 2
a)\(\frac{9}{22}x\frac{33}{18}\)
=\(\frac{9}{22}x\frac{11}{6}\)
=\(\frac{3}{4}\)
b)\(\frac{12}{35}:\frac{36}{25}\)
=\(\frac{12}{35}x\frac{25}{36}\)
=\(\frac{5}{21}\)
c)\(\frac{19}{17}:\frac{76}{51}\)
=\(\frac{19}{17}x\frac{51}{76}\)
=\(\frac{3}{4}\)
