\(17,08\times\left(43-21\right)+22\times2,92\)
\(=22\times\left(17,08+2,92\right)\)
\(=22\times20=440\)
43.17,08 - 21. 17,08 + 22. 2,92 = 17,08. ( 43 -21 ) + 22. 2,92
= 17,08. 22 + 22. 2,92
= 22. (17,08 + 2,92 )
= 22. 20
= 440
43 x 17,08 - 21 x 17,08 + 22 x 2,92
=17,08 x ( 43 - 21 ) + 22 x 2,92
=17,08 x 22 + 22 x 2,92
= 22 x ( 17,08 + 2,92 )
= 22 x 20
= 440
