Question

the ratio of weight of an object on planet A to the weight of the same object on planet B is 100 to 3. if an elephant weights 2200 pounds on planet A finf the elephant weight on planet B

Answer 1

Make a proportion.

$\frac{planet A}{planet B}$ ⇒ $\frac{100}{3}$ = $\frac{2200}{x}$
Solve for x to find the weight of the elephant on planet B. Cross multiply; (100)(x) and (3)(2200).

You now have:
 100x = 6600.
Divide both sides by 100.

x = 66

The elephant would weigh 66 pounds on planet B.
