A simple way to look at how to check for equivalent fractions<span> is to do what is called “cross-multiply”, which means multiple the numerator </span>of<span> one </span>fraction <span>by the denominator </span>of<span> the </span>other fraction<span>. Then do the same thing in reverse. Now compare the two answers to see </span>if<span> they are </span>equal<span>.</span>
Hello!
Multiply the amount of bags Mr. Eaton bought by the amount of pounds each bag weighs:
