a.  4/5 x 350 = 70×4=280
4/5 x 225 = 45×4 = 180
4/5 x 345 = 69 x4 = 276
4/5 x 215 = 43 x 4 = 172
4/5 x 130 = 26 x 4 = 104
b. 9/5 x (330 + 32) = 9/5 x 362 = 651,6
9/5 x (273 + 32) = 9/5 x 305 = 549
9/5 x (373 + 32) = 9/5 x 405 = 729
9/5 x (280 + 32) = 9/5 x 312 = 561,6
9/5 x (325 + 32) = 9/5 x 357 = 642,6
