= (26/15-7/15):19/45
=\(\dfrac{19}{15}:\dfrac{19}{45}\)
=\(\dfrac{19}{15}x\dfrac{45}{19}=\dfrac{45}{15}=3\)
= ( 26/15 - 7/15 ) : 19/45
= 19/15 : 19/15
=1
\(\dfrac{26}{15}:\dfrac{19}{45}-\dfrac{7}{15}:\dfrac{19}{45}\)
\(=\left(\dfrac{26}{15}-\dfrac{7}{15}\right):\dfrac{19}{45}\)
\(=\dfrac{19}{15}:\dfrac{19}{45}\)
\(=\dfrac{19}{15}\) x \(\dfrac{45}{19}\)
\(=\dfrac{855}{285}=3\)
