Need asap ! during a science experiment, martine recorded the masses of five powders she mixed together and dissolved in water. her measurements are shown in the chart. martine then added up the amounts to find the total mass of the chart. martine then added up the amounts to find the total mass of the dissolved. materiel a 3 1/2 g material b 5 3/4 g material c 8 1/2 g material d 2 1/4 g materiel e 7 2/3 g which expression would make finding the sum of these five numbers as easy as possible? a) (3 1/2 + 5 3/4) + (8 1/2 + 2 1/4) + 7 2/3 b) (2 1/4 + 3 1/2) + (5 3/4 + 7 2/3) + 8 1/2 c) (3 1/2 + 8 1/2) + (5 3/4 + 2 1/4) + 7 2/3 d) (3 1/2 + 5 3/4 + 8 1/2 + 2 1/4) + 7 2/3
