Answer 2

In the given question, we have to find the weight of 93 pound person on moon.

We will use unitary method to solve this problem.

"The unitary method is a technique which is used for solving a problem by finding the value of a single unit, i.e., 1, (by dividing) and then finding the necessary value by multiplying the single unit value".

Weight of person on moon with 120 pounds on earth = 20 pounds on moon

Weight of person on moon with 1 pound on earth = $\frac{20}{120}$ pound on moon

Weight of person on moon with 1 pound on earth = $\frac{1}{6}$ pound on moon

Now, Weight of person on moon with 93 pounds on earth = $\frac{1}{6} \times 93$

= $\frac{93}{6}$

= 15.5 pounds.

So, a 93 pound person on earth weighs 15.5 pounds on moon.
