If a crate contains 25,500 oz of rice , about how many kg does it contains ? 1 pound equals 16 oz & 1 pound equals 0.454 kg 351 kg 724 kg 25500 kg 185000 kg

You have ounces and you want kilograms, so you need to multiply by a conversion factor that has ounces in the denominator and kilograms in the numerator. In order to keep from changing the value of the quantity you have, the conversion factor must have equivalent quantities in the numerator and denominaotr.

Your problem statement tells you that both 0.454 kg and 16 oz are equal to a pound, so they are also equal to each other. Their ratio (with kg on top and oz on the bottom) is a suitable conversion factor.

 

The best choice is ...
  724 kg

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
