\(\dfrac{2}{49}\) x 121 : \(\dfrac{22}{7}\)
= \(\dfrac{2}{49}\) x 121 x \(\dfrac{7}{22}\)
= \(\dfrac{2}{7\times7}\) \(\times\)\(\dfrac{11\times11\times7}{11\times2}\)
= \(\dfrac{11}{7}\)
\(\dfrac{2}{49}\times121:\dfrac{22}{7}\)
\(=\dfrac{2\times121}{49}\times\dfrac{7}{22}\)
\(=\dfrac{2\times121\times7}{49\times22}\)
\(=\dfrac{2\times11\times11\times7}{7\times7\times22}\)
\(=\dfrac{22\times11}{7\times22}\)
\(=\dfrac{11}{7}\)
\(\dfrac{2}{49}\times121:\dfrac{22}{7}\)
\(=\dfrac{2\times121}{49}\times\dfrac{7}{22}\)
\(=\dfrac{2\times121\times7}{49\times22}\)
\(=\dfrac{11}{7}\)
