Question

\(\dfrac{5}{2}x4\) = ?

2-\(\dfrac{7}{8}\) = ?

\(\dfrac{9}{4}-2=?\)

\(\dfrac{5}{6}:\dfrac{2}{7}=?\)

Answer 1

10

9/8

1/4

35/12

Answer 2

`5/2xx4=5xx2=10`

`2-7/8=16/8-7/8=9/8`

`9/4-2=9/4-8/4=1/4`

`5/6:2/7=5/6xx7/2=35/12`

Answer 3

\(\dfrac{5}{2}\times4=10\)

\(2-\dfrac{7}{8}=\dfrac{9}{8}\)

\(\dfrac{9}{4}-2=\dfrac{1}{4}\)

\(\dfrac{5}{6}:\dfrac{2}{7}=\dfrac{35}{12}\)

Answer 4

\(\dfrac{5}{2}\times4=\dfrac{5\times4}{2}=\dfrac{20}{2}=10\)

 

\(2-\dfrac{7}{8}=\dfrac{16}{8}-\dfrac{7}{8}=\dfrac{9}{8}\)

 

\(\dfrac{9}{4}-2=\dfrac{9}{4}-\dfrac{8}{4}=\dfrac{1}{4}\)

 

\(\dfrac{5}{6}:\dfrac{2}{7}=\dfrac{5}{6}\times\dfrac{7}{2}=\dfrac{35}{12}\)

Answer 5

\(=\dfrac{20}{2}=10\)

\(=\dfrac{16}{8}-\dfrac{7}{8}=\dfrac{9}{8}\)

\(=\dfrac{9}{4}-\dfrac{8}{4}=\dfrac{1}{4}\)

\(=\dfrac{5}{6}x\dfrac{7}{2}=\dfrac{35}{12}\)

Answer 6

\(\dfrac{5}{2}\times4=\dfrac{20}{2}=10\)

\(2-\dfrac{7}{8}=\dfrac{2}{1}-\dfrac{7}{8}=\dfrac{16}{8}-\dfrac{7}{8}=\dfrac{9}{8}\)

\(\dfrac{9}{4}-\dfrac{2}{1}=\dfrac{9}{4}-\dfrac{8}{4}=\dfrac{1}{4}\)

\(\dfrac{5}{6}:\dfrac{2}{7}=\dfrac{35}{12}\)

Answer 7

\(\dfrac{5x4}{2}=\dfrac{20}{2}=10\)
\(\dfrac{2}{1}-\dfrac{7}{8}=\dfrac{16}{8}-\dfrac{7}{8}=\dfrac{9}{8}\)
\(\dfrac{9}{4}-\dfrac{2}{1}=\dfrac{9}{4}-\dfrac{8}{4}=\dfrac{1}{4}\)
\(\dfrac{5}{6}x\dfrac{7}{2}=\dfrac{35}{12}\)

Answer 8

\(\dfrac{2}{5}\times4=\dfrac{2}{5}\times\dfrac{4}{1}=\dfrac{8}{5}\)

\(2-\dfrac{7}{8}=\dfrac{2}{1}-\dfrac{7}{8}=\dfrac{16}{8}-\dfrac{7}{8}=\dfrac{9}{8}\)

\(\dfrac{9}{4}-2=\dfrac{9}{4}-\dfrac{2}{1}=\dfrac{9}{4}-\dfrac{8}{4}=\dfrac{1}{4}\)

\(\dfrac{5}{6}:\dfrac{2}{7}=\dfrac{5}{6}\times\dfrac{7}{2}=\dfrac{35}{12}\)
