subtracted the numerator and
the denominator and did not find
common denominator
Why do we have to 5pt
multiply the numerator
and the denominator
by the same number
when writing
equivalent fractions?
5pt
If we did not then we would
not be multiplying by a fraction
equivalent to 1 and therefore it
would not be the multiplicative
identity and thus it would
change the value of the
fraction
