The diameter of an Oreo cookie is inches
long. The diameter of an ACME cookie is inches long. If you do not
have the cookies to physically compare, how can you determine which cookie is
bigger (i.e., which has the bigger diameter)? You can compare the fractions. One
way to make this comparison is to find the least common denominator of the
fractions. The LCM of 4 and 5 is 20. So,
and .
Since , then .
Therefore, the ACME cookies have a bigger diameter
than the Oreo cookies.
