There are 240 third grade students at Heesu's school. If the number of third grade students who were glasses is 3/5 of the number of students who do not were glasses, how may third grade students do not were glasses?
240 1 3/5 [OP_ADD] [OP_DIV]
var_a = 240
var_b = 1
var_c = 0.6
var_d = var_b + var_c
var_e = var_a / var_d
print(int(var_e))
