Answer: 345
Step-by-step explanation: We have an equation: 5/100 = 17.25/?
Cross multiply:
5*? = 17.25*100
⇒ ? = 17.25*100/5= 345
345 lb of sea water will be needed in order to get 17.25 lb of salt
When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(they have the same base of x)
(you can't combine the exponents because they have different bases of y and x)
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or
or
Add the exponents together
Make the exponent positive
