Раскройте скобки и приведите подобные слагаемые: 2/9*(1,8m-5,4)-3/7*(2,1m-4,2)

2007Albina 2/9 * (1,8m - 5.4) - 3/7 * (2.1m - 4.2) =
= 2/9 * 18/10 * m - 2/9 * 54/10 - 3/7 * 21/10 * m - 3/7 * (-42/10) =
= (2*2) /10 * m - (2*6)/10 - (3*3) /10 * m + (3*6)/10 =
= 0.4m - 1.2 - 0.9m + 1.8 =
= - (0.9 -0.4)m + (1.8-1.2) =
= -0.5m + 0.6
