\(20,14\times3+20,14\div0,2+20,14\div0,5\)
\(=20,14\times3+20,14\div\dfrac{1}{5}+20,14\div\dfrac{1}{2}\)
\(=20,14\times3+20,14\times5+20,14\times2\)
\(=20,14\times\left(3+5+2\right)\)
\(=20,14\times10\)
\(=201,4\)
20,14 x 3 + 20,14 : 0,2 + 20,14 : 0,5
= 20,14 x 3 + 20,14 : \(\dfrac{1}{5}\) + 20,14 : \(\dfrac{1}{2}\)
= 20,14 x 3 + 20,14 x 5 + 20,14 x 2
= 20,14 x ( 3 + 5 + 2 )
= 20,14 x 10
= 201,4
