Question

The ratio of an object's weight on Earth to its weight on Neptune is 5 : 7. How much would a person who weighs 150 pounds on Earth weigh on Neptune?
A. 107 1/7 pounds
B. 170 pounds
C. 210 pounds
D. 750 pounds

Answer 1

5/7 = 150/x
so solve for x
x= 210

Answer 2

\(\dfrac{5}{7} = \dfrac{150}{x}\)

Cross multiply and then divide.
\(5x=150\times7\)

\(x=\dfrac{150\times7}{5}\)
