When we weighed 9 robots of the same weight and 7 tops also of the same weight in total, it was 10.98 kilograms (kg). If the weight of one robot is 0.8 kilograms (kg), find the weight of one top in kilograms (kg).
10.98 0.8 9 [OP_MUL] [OP_SUB] 7 [OP_DIV]
var_a = 10.98
var_b = 0.8
var_c = 9
var_d = var_b * var_c
var_e = var_a - var_d
var_f = 7
var_g = var_e / var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
