a certain lab experiments with white and brown mice only . in one experiment , 2 / 4 of the mice are white . if there are 16 brown mice in the experiment , how many mice in total are in the experiment ?
"let total number of mice = m number of white mice = 2 / 4 m number of brown mice = 2 / 4 m = 16 = > m = 32 answer a"
subtract(divide(16, divide(2, 4)), 16)
