Because they are the same equation, just rewritten in a different way.
s = 4p
divide both sides by 4 to get the other equation:
(1/4)s = p
Step-by-step explanation:
to convert pounds into ounces you'd
actually multiply 16 by 30:
30 * 16
you're doing this because if one pound equals 16 ounces, if you have 30 pounds then you must've had more ounces. therefore you'd multiply.
which is 480 pounds
Enjoy!
