Write down an equation with the missing element to be the numerator like:

1 pound / \$3.55 = x pounds / \$12

then solve the equation

(1 pound / \$3.55 ) * \$12 = x pounds = 3.38 pounds

This always works for similar situations.

Do \$3.55*12=x

solve for x then round.

Or at least that is how I was taught.:)

Big hint for younger members and guests:

Kurt can buy one pound of nails for \$3.55. How many pounds of nails can Kurt buy for \$12? Round to the nearest hundredth.

Many of you are really confused as to whether you should multiply or divide or perhaps do something else.

The BEST way to  deal with this dilemma is to substitute easy numbers for the hard ones and see what you would do.

SO I might change  this question to

Kurt can buy one pound of nails for \$6   many pounds of nails can Kurt buy for \$12? Round to the nearest hundredth.

Well now the answer is pretty obvious it is 2 ofcourse because 2*6=12

BUT

how can we put 6 and 12 together to get 2.

well 12  ÷ 6 = 2      So it is division!!!

12  ÷ 3.55 will be the answer!

12/3.55 = 3.3802816901408451

So he can buy 3.38 pounds of nails!
