Question

a) \(\frac{2}{3}+\frac{4}{5}=\)

b)\(\frac{5}{12}+\frac{1}{6}=\)

c) \(\frac{3}{4}+\frac{5}{6}=\)

Bằng mấy!!!

Answer 1

\(a,\frac{2}{3}+\frac{4}{5}=\frac{10}{15}+\frac{12}{15}=\frac{22}{15}\)

\(b,\frac{5}{12}+\frac{1}{6}=\frac{5}{12}+\frac{2}{12}=\frac{7}{12}\)

\(c,\frac{3}{4}+\frac{5}{6}=\frac{9}{12}+\frac{10}{12}=\frac{19}{12}\)

Answer 2

a)22/15

b)7/12

c)19/12

Answer 3

\(a\))\(\frac{2}{3}+\frac{4}{5}=\frac{10}{15}+\frac{12}{15}=\frac{22}{15}\)

b) \(\frac{5}{12}+\frac{1}{6}=\frac{5}{12}+\frac{2}{12}=\frac{7}{12}\)

c)\(\frac{3}{4}+\frac{5}{6}=\frac{9}{12}+\frac{10}{12}=\frac{19}{12}\)

Answer 4

2/3+4/5=10/15+12/15=22/15

5/12+1/6=5/12+2/12=7/12

3/4+5/6=9/12+10/12=19/12

quá dễ

Answer 5

a) 10/15 + 12/15 = 22/15

 b) 5/12 + 2/12 = 7/12

c) 9/12 + 10/12 = 19/12

Answer 6

a)\(\frac{2}{3}+\frac{3}{4}=\frac{8+9}{12}=\frac{17}{12}\)

b)  \(\frac{5}{12}+\frac{1}{6}=\frac{5+2}{12}=\frac{7}{12}\)

c)   \(\frac{3}{4}+\frac{5}{6}=\frac{9+10}{12}=\frac{19}{12}\)

Answer 7

a)\(\frac{2}{3}\)+\(\frac{4}{5}\)=\(\frac{10}{15}\)+\(\frac{12}{15}\)=\(\frac{22}{15}\)

b)\(\frac{5}{12}\)+\(\frac{1}{6}\)=\(\frac{5}{12}\)+\(\frac{2}{12}\)=\(\frac{7}{12}\)

c)\(\frac{3}{4}\)+\(\frac{5}{6}\)=\(\frac{9}{12}\)+\(\frac{10}{12}\)=\(\frac{19}{12}\)
