Problem Statement

Person A decided to investigate the relationship between the power consumption of an electrical appliance and the amount of electrical energy consumed.

(1) A fan with an average power consumption of P0P_0P0​ was used for a time T0T_0T0​. How much electrical energy, in J\mathrm{J}J, did the fan consume during this time?

(2) An air conditioner with an operating current of I1I_1I1​ and a voltage of V1V_1V1​ was used for a time T1T_1T1​. What is the average power consumption of this air conditioner in W\mathrm{W}W?

(3) In the case described in (2), how much electrical energy did the air conditioner consume in J\mathrm{J}J?

Constraints

  • P0=50 WP_0 = 50\ \mathrm{W}P0​=50 W
  • T0=5400 sT_0 = 5400\ \mathrm{s}T0​=5400 s
  • I1=20 AI_1 = 20\ \mathrm{A}I1​=20 A
  • V1=200 VV_1 = 200\ \mathrm{V}V1​=200 V
  • T1=1.30×105 sT_1 = 1.30 \times 10^5\ \mathrm{s}T1​=1.30×105 s

Input Format

Let the answer to Part (1) be A1 JA_1\ \mathrm{J}A1​ J, the answer to Part (2) be A2 WA_2\ \mathrm{W}A2​ W, and the answer to Part (3) be A3 JA_3\ \mathrm{J}A3​ J. The dimensionless ratio A3A1×A2\frac{A_3}{A_1 \times A_2}A1​×A2​A3​​ is expressed as the irreducible fraction pq\frac{p}{q}qp​. Find the values of ppp and qqq.
