Respuestas:

17) 234.45+348.00-510.99 = 582.45 - 510.99 = 71.46

18) (0.22+11.99+0.34)+(1.23+4.55+3.77) = 12.55 + 9.55 = 22.1

19) (-12.34-55.67-7.99)+(-6.77+78.99) = -76 +72.22 = -3.78

20) 9*{450.88+312.15-416.77} =9 *{346.26} = 3116.34

21) 8*{111.45+238.77-180.77} =8 * {169.45} = 1355.6

22) 6*[900.34-716.55] = 6 * [183.79] = 1102.74

23)7*(400.23+600.77)+2*(540.22-400.22) = 7007+280 = 7287

24) 9*{1200.45-780.44} =9*{420.01} = 3780.09
