### How can you tell if two fractions are equivalent?

Two fractions are equivalent if the fully simplified fractions
are equal.
If you can multiply the fraction with the smaller numerator and
denominator by the same value to equal the second fraction. For
example the fractions 3/4 and 9/12. The nominator and denominator,
3 and 4 have both been multiplied by 3 to equal 9/12.
Cross multiply. If the products are equal, the fractions are
equal. Cross multiplying means to multiply each numerator of one
fraction with the denominator of the other fraction.

### How do you compare fractions with unlike denominators?

You can cross multiply if there are two fractions to
compare.
EXAMPLE: 1 2 If you multiply the lower right #
__________ = __________ by the upper left # you will get 4
for
2 4 the left side and if you multiply the
lower left by the upper right you will
4 also. compare the numbers for
each side and you get "equal to"
