There was a string that was 70 centimeters (cm) long. Of these, 27 centimeters (cm) was given to Minyoung, and 7/9 of the remaining was used to make (A). How many centimeters (cm) is the length of the remaining string?
70 27 [OP_SUB] 1 7/9 [OP_SUB] [OP_MUL]
var_a = 70
var_b = 27
var_c = var_a - var_b
var_d = 1
var_e = 0.7777777777777778
var_f = var_d - var_e
var_g = var_c * var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
