Question

Tính:

5/7 + 3/14

11/12 - 5/6

6 * 5/8

4/5: 3/7

~Ai làm đúng và nhanh sẽ tick~

Answer 1

\(1,\frac{5}{7}+\frac{3}{14}=\frac{10}{14}+\frac{3}{14}=\frac{13}{14}\)

\(2,\frac{11}{12}-\frac{5}{6}=\frac{11}{12}-\frac{10}{12}=\frac{1}{12}\)

\(3,6.\frac{5}{8}=\frac{30}{8}=\frac{15}{4}\)

\(4,\frac{4}{5}:\frac{3}{7}=\frac{4.7}{5.3}=\frac{28}{15}\)

Answer 2

5/7+3/14=13/14

11/12-5/6=1/12

6*5/8=30/8

4/5:3/7=28/15

Answer 3

1.13/14

2.1/12

3.13/3

4.28/15

Answer 4

\(\frac{5}{7}+\frac{3}{14}=\frac{10}{14}+\frac{3}{14}=\frac{13}{14}\)

\(\frac{11}{12}-\frac{5}{6}=\frac{11}{12}-\frac{10}{12}=\frac{1}{12}\)

\(6\times\frac{5}{8}=\frac{30}{8}=\frac{15}{4}\)

\(\frac{4}{5}\div\frac{3}{7}=\frac{4}{5}\times\frac{7}{3}=\frac{28}{15}\)

Answer 5

a,\(\frac{5}{7}+\frac{3}{14}=\frac{10}{14}+\frac{3}{14}\)

\(=\frac{13}{14}\)

b,\(\frac{11}{12}-\frac{5}{6}=\frac{11}{12}-\frac{10}{12}\)

\(=\frac{1}{12}\)

c,\(\frac{4}{5}:\frac{3}{7}=\frac{4}{5}.\frac{7}{3}\)

\(=\frac{28}{15}\)

d,\(6.\frac{5}{8}=\frac{30}{8}=\frac{15}{4}\)
