There are 7/10 of the air left in the 10 liter (L) bag. How many liters (liters) of air would we need to put in each bag if we wanted to divide this air equally among 4 bags?
10 7/10 [OP_MUL] 4 [OP_DIV]
var_a = 10
var_b = 0.7
var_c = var_a * var_b
var_d = 4
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
