if u read the statment well u will get it multiplying the percentage by 125 means that 58.3 per cent of blood was plasma so 58.3 percent of the 125 is 72.9

no :) its total non sense to divide 125 by 700 because it 125 cm3 of 1200 passes and out of the 1200 blood 700 is plasma ! would not be fear to ignore thwe other substances in the blood !

i calcualted the percentage of plasma in the blood i.e 700\1200x100 =58.3% then 58.3%x125 = 72.9%
