In math class we were all assigned questions and mine was question 13 in section 2.3.
13. The diameter of Pluto is 6/17 the diameter of Mars. Mars is 17/300 the diameter of Saturn.
A) What fraction of the diameter of Saturn is the diameter of Pluto.
Since Pluto is 6/17 of Mars and Mars is 17/300 of Saturn you need to cancel out the 17.
You are left with 6/300 and that is 0.02.
0.02 x 50 = 1
1/50 is the final answer.
B) The diameter of Saturn is 120 000 km. What is the diameter of Pluto?
1/50 = 0.02
120000 x 0.02 = 2400
The diameter of Pluto is 2400km.
