x = 19 080 / 120 = 159
You have to cross multiply by setting the proportion 120/106=180/x(remember you do pound on earth to pounds on earth or pounds on venus to pounds on venus) they you cross multiply 106 times 180 then multiply 120 times x. Then divide the number that has the x next to it 19080/120 = 120x/120 and 19080 divided by 120 is 159. So the answer is B
120
